Title
mlxsw: spectrum_acl_tcam: Fix stack corruption
Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_acl_tcam: Fix stack corruption
When tc filters are first added to a net device, the corresponding local
port gets bound to an ACL group in the device. The group contains a list
of ACLs. In turn, each ACL points to a different TCAM region where the
filters are stored. During forwarding, the ACLs are sequentially
evaluated until a match is found.
One reason to place filters in different regions is when they are added
with decreasing priorities and in an alternating order so that two
consecutive filters can never fit in the same region because of their
key usage.
In Spectrum-2 and newer ASICs the firmware started to report that the
maximum number of ACLs in a group is more than 16, but the layout of the
register that configures ACL groups (PAGT) was not updated to account
for that. It is therefore possible to hit stack corruption [1] in the
rare case where more than 16 ACLs in a group are required.
Fix by limiting the maximum ACL group size to the minimum between what
the firmware reports and the maximum ACLs that fit in the PAGT register.
Add a test case to make sure the machine does not crash when this
condition is hit.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmlxsw: spectrum_acl_tcam: Fix stack corruption\n\nWhen tc filters are first added to a net device, the corresponding local\nport gets bound to an ACL group in the device. The group contains a list\nof ACLs. In turn, each ACL points to a different TCAM region where the\nfilters are stored. During forwarding, the ACLs are sequentially\nevaluated until a match is found.\n\nOne reason to place filters in different regions is when they are added\nwith decreasing priorities and in an alternating order so that two\nconsecutive filters can never fit in the same region because of their\nkey usage.\n\nIn Spectrum-2 and newer ASICs the firmware started to report that the\nmaximum number of ACLs in a group is more than 16, but the layout of the\nregister that configures ACL groups (PAGT) was not updated to account\nfor that. It is therefore possible to hit stack corruption [1] in the\nrare case where more than 16 ACLs in a group are required.\n\nFix by limiting the maximum ACL group size to the minimum between what\nthe firmware reports and the maximum ACLs that fit in the PAGT register.\n\nAdd a test case to make sure the machine does not crash when this\ncondition is hit.\n\n[1]\nKernel panic - not syncing: stack-protector: Kernel stack is corrupted in: mlxsw_sp_acl_tcam_group_update+0x116/0x120\n[...]\n dump_stack_lvl+0x36/0x50\n panic+0x305/0x330\n __stack_chk_fail+0x15/0x20\n mlxsw_sp_acl_tcam_group_update+0x116/0x120\n mlxsw_sp_acl_tcam_group_region_attach+0x69/0x110\n mlxsw_sp_acl_tcam_vchunk_get+0x492/0xa20\n mlxsw_sp_acl_tcam_ventry_add+0x25/0xe0\n mlxsw_sp_acl_rule_add+0x47/0x240\n mlxsw_sp_flower_replace+0x1a9/0x1d0\n tc_setup_cb_add+0xdc/0x1c0\n fl_hw_replace_filter+0x146/0x1f0\n fl_change+0xc17/0x1360\n tc_new_tfilter+0x472/0xb90\n rtnetlink_rcv_msg+0x313/0x3b0\n netlink_rcv_skb+0x58/0x100\n netlink_unicast+0x244/0x390\n netlink_sendmsg+0x1e4/0x440\n ____sys_sendmsg+0x164/0x260\n ___sys_sendmsg+0x9a/0xe0\n __sys_sendmsg+0x7a/0xc0\n do_syscall_64+0x40/0xe0\n entry_SYSCALL_64_after_hwframe+0x63/0x6b"

"value": "AV:L - The vulnerability is reached through the rtnetlink/`tc filter add` path via the `sendmsg()` syscall on a netlink socket, requiring local system access. Network packets traversing the switch cannot reach the ACL group configuration code, which only runs on control-plane filter installation.\nAC:L - The attacker deterministically forces more than 16 ACLs into one group by adding flower filters with decreasing priorities in an alternating key layout so consecutive filters cannot share a TCAM region \u2014 the exact sequence the added selftest performs. There is no race, no timing window, and no dependence on unpredictable memory layout.\nPR:L - `rtnetlink_rcv_msg` gates filter creation on CAP_NET_ADMIN, a delegated capability well short of full root that is routinely granted to network-management daemons and `--net=host --cap-add=NET_ADMIN` containers on the switch platforms where mlxsw is deployed. Such a semi-privileged context crosses a real boundary by smashing the kernel stack.\nUI:N - The attacker installs the tc filters entirely on their own; no victim action, no mount, and no file open is involved. The overflow occurs synchronously inside the attacker\u0027s own syscall.\nS:U - The corrupted memory is the kernel stack of the calling thread, and the impact stays within the kernel\u0027s own security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - Each out-of-bounds iteration read-modify-writes stack memory beyond the 112-byte `pagt_pl` buffer, and the resulting corruption of saved registers and the return address is the kind of memory corruption that can be steered toward disclosing kernel memory. Per the higher-severity rule for out-of-bounds writes on the kernel stack, this is scored High.\nI:H - This is an out-of-bounds write that walks linearly past the end of a fixed 112-byte stack buffer, overwriting the stack canary, saved registers, and return address with values partially controlled by the attacker (region IDs and the `multi` bit). Out-of-bounds writes into a kernel stack frame are treated as High integrity impact.\nA:H - The documented and reproducible outcome is `Kernel panic - not syncing: stack-protector: Kernel stack is corrupted`, an unconditional panic that takes down the entire switch. The condition is triggered on demand and repeatably."

Title
netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout
While the rhashtable set gc runs asynchronously, a race allows it to
collect elements from anonymous sets with timeouts while it is being
released from the commit path.
Mingi Cho originally reported this issue in a different path in 6.1.x
with a pipapo set with low timeouts which is not possible upstream since
7395dfacfff6 ("netfilter: nf_tables: use timestamp to check for set
element timeout").
Fix this by setting on the dead flag for anonymous sets to skip async gc
in this case.
According to 08e4c8c5919f ("netfilter: nf_tables: mark newset as dead on
transaction abort"), Florian plans to accelerate abort path by releasing
objects via workqueue, therefore, this sets on the dead flag for abort
path too.

"value": "AV:L - The vulnerability is reached through the nfnetlink/nftables netlink socket interface (NFNL_SUBSYS_NFTABLES batch transactions) plus locally generated packets traversing the attacker\u0027s own chain, requiring local system access. Per kernel scoring guidance, netfilter/nftables netlink paths are Local.\nAC:L - The attacker controls both sides of the race: they create the anonymous meter set, choose the element timeouts that drive the async rhashtable GC worker (which fires every HZ since anonymous sets force gc_int=0), and choose exactly when to issue the rule-delete transaction that unbinds and asynchronously destroys the set. Failed attempts are harmless and the sequence can be repeated indefinitely with many parallel meter sets, so the race is reliably winnable.\nPR:L - The nftables netlink path only checks netlink_net_capable(skb, CAP_NET_ADMIN), which is evaluated against the owning user namespace of the network namespace, so an unprivileged user obtains it with `unshare -Urn` and nf_tables is fully per-netns. No real root in the initial namespace is needed.\nUI:N - The entire sequence \u2014 creating the meter rule, generating traffic to populate the set, and deleting the rule \u2014 is performed by the attacker\u0027s own process. No victim action of any kind is involved.\nS:U - The use-after-free and double-free occur in kernel heap memory within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed. This is a standard kernel-local privilege escalation primitive.\nC:H - The freed nft_rhash_elem objects carry attacker-sized and attacker-controlled key/data, so the UAF permits reallocating the freed slab object with adjacent kernel data and reading it back through set-element dumps (NFT_MSG_GETSETELEM), yielding arbitrary kernel memory disclosure. Per guidance, any use-after-free is scored High.\nI:H - The concurrent GC removal and rhashtable_free_and_destroy() teardown produce a use-after-free and double-free of slab objects whose size and contents the attacker chooses, a well-established nftables heap-corruption primitive (as in CVE-2023-32233 and CVE-2024-1086) that can be groomed into an arbitrary write and full local privilege escalation.\nA:H - Even without successful exploitation, the UAF/double-free on set elements and the destroyed rhashtable bucket table causes slab corruption, list corruption, and kernel oops/panic. Any kernel crash is scored High."

...
The splat occurs because skb->data points past skb->head allocated area.
This is because neigh layer does:
__skb_pull(skb, skb_network_offset(skb));
... but skb_network_offset() returns a negative offset and __skb_pull()
arg is unsigned. IOW, we skb->data gets "adjusted" by a huge value.
The negative value is returned because skb->head and skb->data distance is
more than 64k and skb->network_header (u16) has wrapped around.
The bug is in the ip_tunnel infrastructure, which can cause
dev->needed_headroom to increment ad infinitum.
The syzkaller reproducer consists of packets getting routed via a gre
tunnel, and route of gre encapsulated packets pointing at another (ipip)
tunnel. The ipip encapsulation finds gre0 as next output device.
This results in the following pattern:
1). First packet is to be sent out via gre0.
Route lookup found an output device, ipip0.
2).
ip_tunnel_xmit for gre0 bumps gre0->needed_headroom based on the future
output device, rt.dev->needed_headroom (ipip0).
3).
ip output / start_xmit moves skb on to ipip0. which runs the same
code path again (xmit recursion).
4).
Routing step for the post-gre0-encap packet finds gre0 as output device
to use for ipip0 encapsulated packet.
tunl0->needed_headroom is then incremented based on the (already bumped)
gre0 device headroom.
This repeats for every future packet:
gre0->needed_headroom gets inflated because previous packets' ipip0 step
incremented rt->dev (gre0) headroom, and ipip0 incremented because gre0
needed_headroom was increased.
For each subsequent packet, gre/ipip0->needed_headroom grows until
post-expand-head reallocations result in a skb->head/data distance of
more than 64k.
Once that happens, skb->network_header (u16) wraps around when
pskb_expand_head tries to make sure that skb_network_offset() is unchanged
after the headroom expansion/reallocation.
After this skb_network_offset(skb) returns a different (and negative)
result post headroom expansion.
The next trip to neigh layer (or anything else that would __skb_pull the
network header) makes skb->data point to a memory location outside
skb->head area.
v2: Cap the needed_headroom update to an arbitarily chosen upperlimit to
prevent perpetual increase instead of dropping the headroom increment
completely.

Title
cifs: fix underflow in parse_server_interfaces()
Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: fix underflow in parse_server_interfaces()
In this loop, we step through the buffer and after each item we check
if the size_left is greater than the minimum size we need. However,
the problem is that "bytes_left" is type ssize_t while sizeof() is type
size_t. That means that because of type promotion, the comparison is
done as an unsigned and if we have negative bytes left the loop
continues instead of ending.

Title
fs: sysfs: Fix reference leak in sysfs_break_active_protection()
Summary
In the Linux kernel, the following vulnerability has been resolved:
fs: sysfs: Fix reference leak in sysfs_break_active_protection()
The sysfs_break_active_protection() routine has an obvious reference
leak in its error path. If the call to kernfs_find_and_get() fails then
kn will be NULL, so the companion sysfs_unbreak_active_protection()
routine won't get called (and would only cause an access violation by
trying to dereference kn->parent if it was called). As a result, the
reference to kobj acquired at the start of the function will never be
released.
Fix the leak by adding an explicit kobject_put() call when kn is NULL.

If the call to kernfs_find_and_get() fails then\nkn will be NULL, so the companion sysfs_unbreak_active_protection()\nroutine won\u0027t get called (and would only cause an access violation by\ntrying to dereference kn-\u003eparent if it was called). As a result, the\nreference to kobj acquired at the start of the function will never be\nreleased.\n\nFix the leak by adding an explicit kobject_put() call when kn is NULL."
