Title
Input: cros_ec_keyb - fix an invalid memory access
Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: cros_ec_keyb - fix an invalid memory access
If cros_ec_keyb_register_matrix() isn't called (due to
`buttons_switches_only`) in cros_ec_keyb_probe(), `ckdev->idev` remains
NULL. An invalid memory access is observed in cros_ec_keyb_process()
when receiving an EC_MKBP_EVENT_KEY_MATRIX event in cros_ec_keyb_work()
in such case.
Unable to handle kernel read from unreadable memory at virtual address 0000000000000028
...
x3 : 0000000000000000 x2 : 0000000000000000
x1 : 0000000000000000 x0 : 0000000000000000
Call trace:
input_event
cros_ec_keyb_work
blocking_notifier_call_chain
ec_irq_thread
It's still unknown about why the kernel receives such malformed event,
in any cases, the kernel shouldn't access `ckdev->idev` and friends if
the driver doesn't intend to initialize them.

Title
be2net: pass wrb_params in case of OS2BMC
Summary
In the Linux kernel, the following vulnerability has been resolved:
be2net: pass wrb_params in case of OS2BMC
be_insert_vlan_in_pkt() is called with the wrb_params argument being NULL
at be_send_pkt_to_bmc() call site. This may lead to dereferencing a NULL
pointer when processing a workaround for specific packet, as commit
bc0c3405abbb ("be2net: fix a Tx stall bug caused by a specific ipv6
packet") states.
The correct way would be to pass the wrb_params from be_xmit().
Severity
No CVSS data available.

Title
ALSA: usb-audio: Fix potential overflow of PCM transfer buffer
Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix potential overflow of PCM transfer buffer
The PCM stream data in USB-audio driver is transferred over USB URB
packet buffers, and each packet size is determined dynamically. The
packet sizes are limited by some factors such as wMaxPacketSize USB
descriptor. OTOH, in the current code, the actually used packet sizes
are determined only by the rate and the PPS, which may be bigger than
the size limit above. This results in a buffer overflow, as reported
by syzbot.
Basically when the limit is smaller than the calculated packet size,
it implies that something is wrong, most likely a weird USB
descriptor. So the best option would be just to return an error at
the parameter setup time before doing any further operations.
This patch introduces such a sanity check, and returns -EINVAL when
the packet size is greater than maxpacksize. The comparison with
ep->packsize[1] alone should suffice since it's always equal or
greater than ep->packsize[0].

Although a malformed descriptor is one way to reach it, no physical interaction is required for a local attacker on a machine with an attached USB audio device.\nAC:L - The attacker deterministically chooses the rate and sample format that make `packsize[1] * stride` exceed the `wMaxPacketSize`-derived buffer, then triggers the copy by starting playback \u2014 no race, no memory-layout guessing, and the condition is fully reproducible on every URB submission.\nPR:L - Only access to the ALSA PCM device node is required, which is granted to the logged-in session user via logind ACLs or membership in the `audio` group; no CAP_SYS_ADMIN or root is needed.\nUI:N - The attacking process performs open/hw_params/prepare/write entirely on its own; no victim action is needed, and on desktop/Android systems PipeWire/AudioFlinger will even drive the stream automatically on hotplug.\nS:U - The corruption stays within the kernel\u0027s own memory and the USB host controller\u0027s DMA-coherent pool, managed by the same security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:H - The oversized `iso_frame_desc` lengths cause the host controller to DMA kernel memory beyond the allocated coherent buffer out to the USB device, disclosing adjacent kernel heap contents to the attacker; heap corruption can also be leveraged for broader arbitrary read.\nI:H - `copy_to_urb()` memcpy\u0027s an attacker-controlled length of attacker-controlled PCM bytes past the end of the coherent URB buffer, giving a heap out-of-bounds write with controlled content \u2014 a primitive suitable for corrupting adjacent objects and hijacking control flow.\nA:H - Overrunning the DMA-coherent transfer buffer corrupts neighbouring kernel/DMA-pool memory and reliably produces an oops or panic, as observed in the syzbot report and the related bugzilla crash reports."

Title
fs/proc: fix uaf in proc_readdir_de()
Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/proc: fix uaf in proc_readdir_de()
Pde is erased from subdir rbtree through rb_erase(), but not set the node
to EMPTY, which may result in uaf access. We should use RB_CLEAR_NODE()
set the erased node to EMPTY, then pde_subdir_next() will return NULL to
avoid uaf access.
We found an uaf issue while using stress-ng testing, need to run testcase
getdent and tun in the same time. The steps of the issue is as follows:
1) use getdent to traverse dir /proc/pid/net/dev_snmp6/, and current
pde is tun3;
2) in the [time windows] unregister netdevice tun3 and tun2, and erase
them from rbtree. erase tun3 first, and then erase tun2. the
pde(tun2) will be released to slab;
3) continue to getdent process, then pde_subdir_next() will return
pde(tun2) which is released, it will case uaf access.

"value": "AV:L - The vulnerability is triggered entirely through local syscalls \u2014 `getdents64(2)` on a procfs directory racing against `unshare(2)`/rtnetlink operations that remove `/proc` entries. No network or remote-peer data is involved.\nAC:L - The attacker owns both sides of the race: one thread iterates `/proc/self/net/dev_snmp6` while another spins netdevice rename/unregister to erase entries, and the `dir_emit()` window can be stretched arbitrarily by backing the `getdents64` buffer with userfaultfd or FUSE so the reader stalls in `copy_to_user` while the neighbour pde is freed and the slab groomed. The sequence is unbounded and retryable.\nPR:L - Reading `/proc/self/net/dev_snmp6` requires no privilege at all, and the removal side needs only `CAP_NET_ADMIN` inside an attacker-created user+network namespace (`unshare -Urn`), which any unprivileged user obtains on default distro configurations. No real root in the init namespace is needed.\nUI:N - The attacker drives both the directory iteration and the proc-entry removal from its own threads; no victim action or cooperation is required.\nS:U - The corruption is confined to kernel heap objects managed by the same kernel security authority; there is no VM, IOMMU, or hypervisor boundary crossed.\nC:H - `dir_emit(ctx, de-\u003ename, de-\u003enamelen, ...)` reads the `char *name` pointer and `u8 namelen` out of the freed `proc_dir_entry` and copies up to 255 bytes from that pointer directly into the user\u0027s dirent buffer, giving a repeatable arbitrary-kernel-memory read into userspace once the slab object is reclaimed with attacker-influenced content.\nI:H - The use-after-free yields `refcount_inc()`/`refcount_dec_and_test()` on freed memory plus `pde_free()` performing `kfree(pde-\u003edata)`/`kfree(pde-\u003ename)` on pointers read from the reallocated object, providing arbitrary-free and heap-corruption primitives that are a standard basis for local privilege escalation.\nA:H - Dereferencing stale rbtree links into freed slab memory reliably produces a kernel oops/panic (as observed under stress-ng with getdents+tun), and the race can be re-run indefinitely to crash the system on demand."

Title
NFSD: free copynotify stateid in nfs4_free_ol_stateid()
Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSD: free copynotify stateid in nfs4_free_ol_stateid()
Typically copynotify stateid is freed either when parent's stateid
is being close/freed or in nfsd4_laundromat if the stateid hasn't
been used in a lease period.
However, in case when the server got an OPEN (which created
a parent stateid), followed by a COPY_NOTIFY using that stateid,
followed by a client reboot. New client instance while doing
CREATE_SESSION would force expire previous state of this client.
It leads to the open state being freed thru release_openowner->
nfs4_free_ol_stateid() and it finds that it still has copynotify
stateid associated with it. We currently print a warning and is
triggerred
WARNING: CPU: 1 PID: 8858 at fs/nfsd/nfs4state.c:1550 nfs4_free_ol_stateid+0xb0/0x100 [nfsd]
This patch, instead, frees the associated copynotify stateid here.
If the parent stateid is freed (without freeing the copynotify
stateids associated with it), it leads to the list corruption
when laundromat ends up freeing the copynotify state later.

Title
ALSA: usb-audio: Fix NULL pointer dereference in snd_usb_mixer_controls_badd
Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix NULL pointer dereference in snd_usb_mixer_controls_badd
In snd_usb_create_streams(), for UAC version 3 devices, the Interface
Association Descriptor (IAD) is retrieved via usb_ifnum_to_if(). If this
call fails, a fallback routine attempts to obtain the IAD from the next
interface and sets a BADD profile. However, snd_usb_mixer_controls_badd()
assumes that the IAD retrieved from usb_ifnum_to_if() is always valid,
without performing a NULL check. This can lead to a NULL pointer
dereference when usb_ifnum_to_if() fails to find the interface descriptor.
This patch adds a NULL pointer check after calling usb_ifnum_to_if() in
snd_usb_mixer_controls_badd() to prevent the dereference.
This issue was discovered by syzkaller, which triggered the bug by sending
a crafted USB device descriptor.
Severity
No CVSS data available.

No victim action or interaction is required.\nS:U - The integer overflow and the resulting out-of-bounds accesses occur within the guest kernel\u0027s own address space and are confined to the kernel\u0027s security authority.

Controlled heap corruption of this kind is a standard path to privilege escalation.\nA:H - A header-\u003esize of 0xFFFFFFF8 makes *size zero, causing vmw_cmd_check_all() to spin forever while holding dev_priv-\u003ecmdbuf_mutex, and the far out-of-bounds reads past a vmalloc\u0027d bounce buffer hit a guard page and oops the kernel.

Title
net: sched: act_ife: initialize struct tc_ife to fix KMSAN kernel-infoleak
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sched: act_ife: initialize struct tc_ife to fix KMSAN kernel-infoleak
Fix a KMSAN kernel-infoleak detected by the syzbot .
[net?] KMSAN: kernel-infoleak in __skb_datagram_iter
In tcf_ife_dump(), the variable 'opt' was partially initialized using a
designatied initializer. While the padding bytes are reamined
uninitialized. nla_put() copies the entire structure into a
netlink message, these uninitialized bytes leaked to userspace.
Initialize the structure with memset before assigning its fields
to ensure all members and padding are cleared prior to beign copied.
This change silences the KMSAN report and prevents potential information
leaks from the kernel memory.
This fix has been tested and validated by syzbot. This patch closes the
bug reported at the following syzkaller link and ensures no infoleak.
Severity
No CVSS data available.

Title
tipc: Fix use-after-free in tipc_mon_reinit_self().
Summary
In the Linux kernel, the following vulnerability has been resolved:
tipc: Fix use-after-free in tipc_mon_reinit_self().
syzbot reported use-after-free of tipc_net(net)->monitors[]
in tipc_mon_reinit_self(). [0]
The array is protected by RTNL, but tipc_mon_reinit_self()
iterates over it without RTNL.
tipc_mon_reinit_self() is called from tipc_net_finalize(),
which is always under RTNL except for tipc_net_finalize_work().
Let's hold RTNL in tipc_net_finalize_work().

Title
sctp: prevent possible shift-out-of-bounds in sctp_transport_update_rto
Summary
In the Linux kernel, the following vulnerability has been resolved:
sctp: prevent possible shift-out-of-bounds in sctp_transport_update_rto
syzbot reported a possible shift-out-of-bounds [1]
Blamed commit added rto_alpha_max and rto_beta_max set to 1000.
It is unclear if some sctp users are setting very large rto_alpha
and/or rto_beta.
In order to prevent user regression, perform the test at run time.
Also add READ_ONCE() annotations as sysctl values can change under us.
