problem. Ido Schimmel found steps to reproduce
ip link add name team1 type team
ip link add name dummy1 mtu 1499 master team1 type dummy
ip netns add ns1
ip link set dev dummy1 netns ns1
ip -n ns1 link del dev dummy1
and also found that the same issue was fixed in the bond driver in
commit f51048c3e07b ("bonding: avoid NETDEV_CHANGEMTU event when
unregistering slave").
Let's do similar thing for the team driver, with commit ad7c7b2172c3 ("net:
hold netdev instance lock during sysfs operations") and commit 303a8487a657
("net: s/__dev_set_mtu/__netif_set_mtu/") also applied.

Title
xfrm: esp: avoid in-place decrypt on shared skb frags
Summary
In the Linux kernel, the following vulnerability has been resolved:
xfrm: esp: avoid in-place decrypt on shared skb frags
MSG_SPLICE_PAGES can attach pages from a pipe directly to an skb. TCP
marks such skbs with SKBFL_SHARED_FRAG after skb_splice_from_iter(),
so later paths that may modify packet data can first make a private
copy. The IPv4/IPv6 datagram append paths did not set this flag when
splicing pages into UDP skbs.
That leaves an ESP-in-UDP packet made from shared pipe pages looking
like an ordinary uncloned nonlinear skb. ESP input then takes the no-COW
fast path for uncloned skbs without a frag_list and decrypts in place
over data that is not owned privately by the skb.
Mark IPv4/IPv6 datagram splice frags with SKBFL_SHARED_FRAG, matching
TCP. Also make ESP input fall back to skb_cow_data() when the flag is
present, so ESP does not decrypt externally backed frags in place.
Private nonlinear skb frags still use the existing fast path.
This intentionally does not change ESP output. In esp_output_head(),
the path that appends the ESP trailer to existing skb tailroom without
calling skb_cow_data() is not reachable for nonlinear skbs:
skb_tailroom() returns zero when skb->data_len is nonzero, while ESP
tailen is positive. Thus ESP output will either use the separate
destination-frag path or fall back to skb_cow_data().

Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The xfrm-ESP variant requires unprivileged user or network namespace creation, while the RxRPC variant depends on the rxrpc module being available on the target system."

Title
wifi: iwlwifi: mvm: don't send a 6E related command when not supported
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: don't send a 6E related command when not supported
MCC_ALLOWED_AP_TYPE_CMD is related to 6E support. Do not send it if the
device doesn't support 6E.
Apparently, the firmware is mistakenly advertising support for this
command even on AX201 which does not support 6E and then the firmware
crashes.
Severity
No CVSS data available.

Title
cpufreq: governor: fix double free in cpufreq_dbs_governor_init() error path
Summary
In the Linux kernel, the following vulnerability has been resolved:
cpufreq: governor: fix double free in cpufreq_dbs_governor_init() error path
When kobject_init_and_add() fails, cpufreq_dbs_governor_init() calls
kobject_put(&dbs_data->attr_set.kobj).
The kobject release callback cpufreq_dbs_data_release() calls
gov->exit(dbs_data) and kfree(dbs_data), but the current error path
then calls gov->exit(dbs_data) and kfree(dbs_data) again, causing a
double free.
Keep the direct kfree(dbs_data) for the gov->init() failure path, but
after kobject_init_and_add() has been called, let kobject_put() handle
the cleanup through cpufreq_dbs_data_release().
Severity
No CVSS data available.

Title
bpf: reject direct access to nullable PTR_TO_BUF pointers
Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: reject direct access to nullable PTR_TO_BUF pointers
check_mem_access() matches PTR_TO_BUF via base_type() which strips
PTR_MAYBE_NULL, allowing direct dereference without a null check.
Map iterator ctx->key and ctx->value are PTR_TO_BUF | PTR_MAYBE_NULL.
On stop callbacks these are NULL, causing a kernel NULL dereference.
Add a type_may_be_null() guard to the PTR_TO_BUF branch, matching the
existing PTR_TO_BTF_ID pattern.
Severity
No CVSS data available.

Title
btrfs: reserve enough transaction items for qgroup ioctls
Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: reserve enough transaction items for qgroup ioctls
Currently our qgroup ioctls don't reserve any space, they just do a
transaction join, which does not reserve any space, neither for the quota
tree updates nor for the delayed refs generated when updating the quota
tree. The quota root uses the global block reserve, which is fine most of
the time since we don't expect a lot of updates to the quota root, or to
be too close to -ENOSPC such that other critical metadata updates need to
resort to the global reserve.
However this is not optimal, as not reserving proper space may result in a
transaction abort due to not reserving space for delayed refs and then
abusing the use of the global block reserve.
For example, the following reproducer (which is unlikely to model any
real world use case, but just to illustrate the problem), triggers such a
transaction abort due to -ENOSPC when running delayed refs:
$ cat test.sh
#!/bin/bash
DEV=/dev/nullb0
MNT=/mnt/nullb0
umount $DEV &> /dev/null
# Limit device to 1G so that it's much faster to reproduce the issue.
mkfs.btrfs -f -b 1G $DEV
mount -o commit=600 $DEV $MNT
fallocate -l 800M $MNT/filler
btrfs quota enable $MNT
for ((i = 1; i <= 400000; i++)); do
btrfs qgroup create 1/$i $MNT
done
umount $MNT
When running this, we can see in dmesg/syslog that a transaction abort
happened:

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: reserve enough transaction items for qgroup ioctls\n\nCurrently our qgroup ioctls don\u0027t reserve any space, they just do a\ntransaction join, which does not reserve any space, neither for the quota\ntree updates nor for the delayed refs generated when updating the quota\ntree. The quota root uses the global block reserve, which is fine most of\nthe time since we don\u0027t expect a lot of updates to the quota root, or to\nbe too close to -ENOSPC such that other critical metadata updates need to\nresort to the global reserve.\n\nHowever this is not optimal, as not reserving proper space may result in a\ntransaction abort due to not reserving space for delayed refs and then\nabusing the use of the global block reserve.\n\nFor example, the following reproducer (which is unlikely to model any\nreal world use case, but just to illustrate the problem), triggers such a\ntransaction abort due to -ENOSPC when running delayed refs:\n\n $ cat test.sh\n #!/bin/bash\n\n DEV=/dev/nullb0\n MNT=/mnt/nullb0\n\n umount $DEV \u0026\u003e /dev/null\n # Limit device to 1G so that it\u0027s much faster to reproduce the issue.\n mkfs.btrfs -f -b 1G $DEV\n mount -o commit=600 $DEV $MNT\n\n fallocate -l 800M $MNT/filler\n btrfs quota enable $MNT\n\n for ((i = 1; i \u003c= 400000; i++)); do\n btrfs qgroup create 1/$i $MNT\n done\n\n umount $MNT\n\nWhen running this, we can see in dmesg/syslog that a transaction abort\nhappened:\n\n [436.490] BTRFS error (device nullb0): failed to run delayed ref for logical 30408704 num_bytes 16384 type 176 action 1 ref_mod 1: -28\n [436.493] ------------[ cut here ]------------\n [436.494] BTRFS: Transaction aborted (error -28)\n [436.495] WARNING: fs/btrfs/extent-tree.c:2247 at btrfs_run_delayed_refs+0xd9/0x110 [btrfs], CPU#4: umount/2495372\n [436.497] Modules linked in: btrfs loop (...)\n [436.508] CPU: 4 UID: 0 PID: 2495372 Comm: umount Tainted: G W 6.19.0-rc8-btrfs-next-225+ #1 PREEMPT(full)\n [436.510] Tainted: [W]=WARN\n [436.511] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.2-0-gea1b7a073390-prebuilt.qemu.org 04/01/2014\n [436.513] RIP: 0010:btrfs_run_delayed_refs+0xdf/0x110 [btrfs]\n [436.514] Code: 0f 82 ea (...)\n [436.518] RSP: 0018:ffffd511850b7d78 EFLAGS: 00010292\n [436.519] RAX: 00000000ffffffe4 RBX: ffff8f120dad37e0 RCX: 0000000002040001\n [436.520] RDX: 0000000000000002 RSI: 00000000ffffffe4 RDI: ffffffffc090fd80\n [436.522] RBP: 0000000000000000 R08: 0000000000000001 R09: ffffffffc04d1867\n [436.523] R10: ffff8f18dc1fffa8 R11: 0000000000000003 R12: ffff8f173aa89400\n [436.524] R13: 0000000000000000 R14: ffff8f173aa89400 R15: 0000000000000000\n [436.526] FS: 00007fe59045d840(0000) GS:ffff8f192e22e000(0000) knlGS:0000000000000000\n [436.527] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n [436.528] CR2: 00007fe5905ff2b0 CR3: 000000060710a002 CR4: 0000000000370ef0\n [436.530] Call Trace:\n [436.530] \u003cTASK\u003e\n [436.530] btrfs_commit_transaction+0x73/0xc00 [btrfs]\n [436.531] ? btrfs_attach_transaction_barrier+0x1e/0x70 [btrfs]\n [436.532] sync_filesystem+0x7a/0x90\n [436.533] generic_shutdown_super+0x28/0x180\n [436.533] kill_anon_super+0x12/0x40\n [436.534] btrfs_kill_super+0x12/0x20 [btrfs]\n [436.534] deactivate_locked_super+0x2f/0xb0\n [436.534] cleanup_mnt+0xea/0x180\n [436.535] task_work_run+0x58/0xa0\n [436.535] exit_to_user_mode_loop+0xed/0x480\n [436.536] ? __x64_sys_umount+0x68/0x80\n [436.536] do_syscall_64+0x2a5/0xf20\n [436.537] entry_SYSCALL_64_after_hwframe+0x76/0x7e\n [436.537] RIP: 0033:0x7fe5906b6217\n [436.538] Code: 0d 00 f7 (...)\n [436.540] RSP: 002b:00007ffcd87a61f8 EFLAGS: 00000246 ORIG_RAX: 00000000000000a6\n [436.541] RAX: 0000000000000000 RBX: 00005618b9ecadc8 RCX: 00007fe5906b6217\n [436.541] RDX: 0000000000000000 RSI: 0000000000000000 RDI: 00005618b9ecb100\n [436.542] RBP: 0000000000000000 R08: 00007ffcd87a4fe0 R09: 00000000ffffffff\n [436.544] R10: 0000000000000103 R11: \n---truncated---"

Title
net/ipv6: ioam6: prevent schema length wraparound in trace fill
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/ipv6: ioam6: prevent schema length wraparound in trace fill
ioam6_fill_trace_data() stores the schema contribution to the trace
length in a u8. With bit 22 enabled and the largest schema payload,
sclen becomes 1 + 1020 / 4, wraps from 256 to 0, and bypasses the
remaining-space check. __ioam6_fill_trace_data() then positions the
write cursor without reserving the schema area but still copies the
4-byte schema header and the full schema payload, overrunning the trace
buffer.
Keep sclen in an unsigned int so the remaining-space check and the write
cursor calculation both see the full schema length.
Severity
9.8 (Critical)

Title
btrfs: fix transaction abort on set received ioctl due to item overflow
Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix transaction abort on set received ioctl due to item overflow
If the set received ioctl fails due to an item overflow when attempting to
add the BTRFS_UUID_KEY_RECEIVED_SUBVOL we have to abort the transaction
since we did some metadata updates before.
This means that if a user calls this ioctl with the same received UUID
field for a lot of subvolumes, we will hit the overflow, trigger the
transaction abort and turn the filesystem into RO mode. A malicious user
could exploit this, and this ioctl does not even requires that a user
has admin privileges (CAP_SYS_ADMIN), only that he/she owns the subvolume.
Fix this by doing an early check for item overflow before starting a
transaction. This is also race safe because we are holding the subvol_sem
semaphore in exclusive (write) mode.
A test case for fstests will follow soon.

Title
btrfs: fix transaction abort on file creation due to name hash collision
Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix transaction abort on file creation due to name hash collision
If we attempt to create several files with names that result in the same
hash, we have to pack them in same dir item and that has a limit inherent
to the leaf size. However if we reach that limit, we trigger a transaction
abort and turns the filesystem into RO mode. This allows for a malicious
user to disrupt a system, without the need to have administration
privileges/capabilities.
Reproducer:
$ cat exploit-hash-collisions.sh
#!/bin/bash
DEV=/dev/sdi
MNT=/mnt/sdi
# Use smallest node size to make the test faster and require fewer file
# names that result in hash collision.
mkfs.btrfs -f --nodesize 4K $DEV
mount $DEV $MNT
# List of names that result in the same crc32c hash for btrfs.
declare -a names=(

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: fix transaction abort on file creation due to name hash collision\n\nIf we attempt to create several files with names that result in the same\nhash, we have to pack them in same dir item and that has a limit inherent\nto the leaf size. However if we reach that limit, we trigger a transaction\nabort and turns the filesystem into RO mode. This allows for a malicious\nuser to disrupt a system, without the need to have administration\nprivileges/capabilities.\n\nReproducer:\n\n $ cat exploit-hash-collisions.sh\n #!/bin/bash\n\n DEV=/dev/sdi\n MNT=/mnt/sdi\n\n # Use smallest node size to make the test faster and require fewer file\n # names that result in hash collision.\n mkfs.btrfs -f --nodesize 4K $DEV\n mount $DEV $MNT\n\n # List of names that result in the same crc32c hash for btrfs.\n declare -a names=(\n \u0027foobar\u0027\n \u0027%a8tYkxfGMLWRGr55QSeQc4PBNH9PCLIvR6jZnkDtUUru1t@RouaUe_L:@xGkbO3nCwvLNYeK9vhE628gss:T$yZjZ5l-Nbd6CbC$M=hqE-ujhJICXyIxBvYrIU9-TDC\u0027\n \u0027AQci3EUB%shMsg-N%frgU:02ByLs=IPJU0OpgiWit5nexSyxZDncY6WB:=zKZuk5Zy0DD$Ua78%MelgBuMqaHGyKsJUFf9s=UW80PcJmKctb46KveLSiUtNmqrMiL9-Y0I_l5Fnam04CGIg=8@U:Z\u0027\n \u0027CvVqJpJzueKcuA$wqwePfyu7VxuWNN3ho$p0zi2H8QFYK$7YlEqOhhb%:hHgjhIjW5vnqWHKNP4\u0027\n \u0027ET:vk@rFU4tsvMB0$C_p=xQHaYZjvoF%-BTc%wkFW8yaDAPcCYoR%x$FH5O:\u0027\n \u0027HwTon%v7SGSP4FE08jBwwiu5aot2CFKXHTeEAa@38fUcNGOWvE@Mz6WBeDH_VooaZ6AgsXPkVGwy9l@@ZbNXabUU9csiWrrOp0MWUdfi$EZ3w9GkIqtz7I_eOsByOkBOO\u0027\n \u0027Ij%2VlFGXSuPvxJGf5UWy6O@1svxGha%b@=%wjkq:CIgE6u7eJOjmQY5qTtxE2Rjbis9@us\u0027\n \u0027KBkjG5%9R8K9sOG8UTnAYjxLNAvBmvV5vz3IiZaPmKuLYO03-6asI9lJ_j4@6Xo$KZicaLWJ3Pv8XEwVeUPMwbHYWwbx0pYvNlGMO9F:ZhHAwyctnGy%_eujl%WPd4U2BI7qooOSr85J-C2V$LfY\u0027\n \u0027NcRfDfuUQ2=zP8K3CCF5dFcpfiOm6mwenShsAb_F%n6GAGC7fT2JFFn:c35X-3aYwoq7jNX5$ZJ6hI3wnZs$7KgGi7wjulffhHNUxAT0fRRLF39vJ@NvaEMxsMO\u0027\n \u0027Oj42AQAEzRoTxa5OuSKIr=A_lwGMy132v4g3Pdq1GvUG9874YseIFQ6QU\u0027\n \u0027Ono7avN5GjC:_6dBJ_\u0027\n \u0027WHmN2gnmaN-9dVDy4aWo:yNGFzz8qsJyJhWEWcud7$QzN2D9R0efIWWEdu5kwWr73NZm4=@CoCDxrrZnRITr-kGtU_cfW2:%2_am\u0027\n \u0027WiFnuTEhAG9FEC6zopQmj-A-$LDQ0T3WULz%ox3UZAPybSV6v1Z$b4L_XBi4M4BMBtJZpz93r9xafpB77r:lbwvitWRyo$odnAUYlYMmU4RvgnNd--e=I5hiEjGLETTtaScWlQp8mYsBovZwM2k\u0027\n \u0027XKyH=OsOAF3p%uziGF_ZVr$ivrvhVgD@1u%5RtrV-gl_vqAwHkK@x7YwlxX3qT6WKKQ%PR56NrUBU2dOAOAdzr2=5nJuKPM-T-$ZpQfCL7phxQbUcb:BZOTPaFExc-qK-gDRCDW2\u0027\n \u0027d3uUR6OFEwZr%ns1XH_@tbxA@cCPmbBRLdyh7p6V45H$P2$F%w0RqrD3M0g8aGvWpoTFMiBdOTJXjD:JF7=h9a_43xBywYAP%r$SPZi%zDg%ql-KvkdUCtF9OLaQlxmd\u0027\n \u0027ePTpbnit%hyNm@WELlpKzNZYOzOTf8EQ$sEfkMy1VOfIUu3coyvIr13-Y7Sv5v-Ivax2Go_GQRFMU1b3362nktT9WOJf3SpT%z8sZmM3gvYQBDgmKI%%RM-G7hyrhgYflOw%z::ZRcv5O:lDCFm\u0027\n \u0027evqk743Y@dvZAiG5J05L_ROFV@$2%rVWJ2%3nxV72-W7$e$-SK3tuSHA2mBt$qloC5jwNx33GmQUjD%akhBPu=VJ5g$xhlZiaFtTrjeeM5x7dt4cHpX0cZkmfImndYzGmvwQG:$euFYmXn$_2rA9mKZ\u0027\n \u0027gkgUtnihWXsZQTEkrMAWIxir09k3t7jk_IK25t1:cy1XWN0GGqC%FrySdcmU7M8MuPO_ppkLw3=Dfr0UuBAL4%GFk2$Ma10V1jDRGJje%Xx9EV2ERaWKtjpwiZwh0gCSJsj5UL7CR8RtW5opCVFKGGy8Cky\u0027\n \u0027hNgsG_8lNRik3PvphqPm0yEH3P%%fYG:kQLY=6O-61Wa6nrV_WVGR6TLB09vHOv%g4VQRP8Gzx7VXUY1qvZyS\u0027\n \u0027isA7JVzN12xCxVPJZ_qoLm-pTBuhjjHMvV7o=F:EaClfYNyFGlsfw-Kf%uxdqW-kwk1sPl2vhbjyHU1A6$hz\u0027\n \u0027kiJ_fgcdZFDiOptjgH5PN9-PSyLO4fbk_:u5_2tz35lV_iXiJ6cx7pwjTtKy-XGaQ5IefmpJ4N_ZqGsqCsKuqOOBgf9LkUdffHet@Wu\u0027\n \u0027lvwtxyhE9:%Q3UxeHiViUyNzJsy:fm38pg_b6s25JvdhOAT=1s0$pG25x=LZ2rlHTszj=gN6M4zHZYr_qrB49i=pA--@WqWLIuX7o1S_SfS@2FSiUZN\u0027\n \u0027rC24cw3UBDZ=5qJBUMs9e$=S4Y94ni%Z8639vnrGp=0Hv4z3dNFL0fBLmQ40=EYIY:Z=SLc@QLMSt2zsss2ZXrP7j4=\u0027\n \u0027uwGl2s-fFrf@GqS=DQqq2I0LJSsOmM%xzTjS:lzXguE3wChdMoHYtLRKPvfaPOZF2fER@j53evbKa7R%A7r4%YEkD=kicJe@SFiGtXHbKe4gCgPAYbnVn\u0027\n \u0027UG37U6KKua2bgc:IHzRs7BnB6FD:2Mt5Cc5NdlsW%$1tyvnfz7S27FvNkroXwAW:mBZLA1@qa9WnDbHCDmQmfPMC9z-Eq6QT0jhhPpqyymaD:R02ghwYo%yx7SAaaq-:x33LYpei$5g8DMl3C\u0027\n \u0027y2vjek0FE1PDJC0qpfnN:x8k2wCFZ9xiUF2ege=JnP98R%wxjKkdfEiLWvQzmnW\u0027\n \u00278-HCSgH5B%K7P8_jaVtQhBXpBk:pE-$P7ts58U0J@iR9YZntMPl7j$s62yAJO@_9eanFPS54b=UTw$94C-t=HLxT8n6o9P=QnIxq-f1=Ne2dvhe6WbjEQtc\u0027\n \u0027YPPh:IFt2mtR6XWSmjHptXL_hbSYu8bMw-JP8@PNyaFkdNFsk$M=xfL6LDKCDM-mSyGA_2MBwZ8Dr4=R1D%7-mC\n---truncated---"
