octeontx2-af: npc: Fix size of entry2cntr_map
KASAN prints below splat. This is caused by allocating counter for
reserved mcam entry for cpt 2nd pass entry. But mcam->entry2cntr_map
is not allocated for reserved entries.

tas2562_volume_control_put() does not do any validation of the control
value written by userspace, it uses it to look up a value in a fixed

ixgbe: do not configure xps for XDP queues
netif_set_xps_queue() should not be called for an XDP Tx queue, since such
queues are not netdev-exposed. On systems with number of CPUs >=64, on E610
adapter, netdev is configured with maximum number queue pairs being 63
(due to MSI-X assignment), but configuring XDP results in 64 XDP queues.
So, during XDP program load, when netif_set_xps_queue() is called for the
last XDP queue, we get a WARNING with a call trace and KASAN report
afterwards (if enabled).

| In the Linux kernel, the following vulnerability has been resolved:
bpf: Guard conntrack opts error writes
The conntrack lookup and allocation kfuncs take an opts pointer
together with an opts__sz argument. The verifier checks only the memory
range described by opts__sz, but the wrappers unconditionally write
opts->error whenever the internal lookup or allocation helper returns an
error.
For an invalid size smaller than the end of opts->error, that write can
land outside the verifier-checked range. Keep returning NULL for invalid
arguments, but only report the error through opts->error when the
supplied size includes the field.
This preserves error reporting for the supported 12-byte and 16-byte
layouts, and for other invalid sizes that still include opts->error. |
| In the Linux kernel, the following vulnerability has been resolved:
xen/pvcalls: bound backend response req_id before indexing rsp[]
pvcalls_front_event_handler() takes req_id directly from the
backend-supplied ring response and uses it to index the fixed-size
bedata->rsp[] array for a memcpy() and a store, with no range check. A
malicious or buggy backend can set req_id past PVCALLS_NR_RSP_PER_RING
and drive an out-of-bounds write past the bedata allocation.
req_id was also declared int while the wire field rsp->req_id is u32, so
a range check on the signed value alone is insufficient: a backend
req_id of 0xffffffff becomes -1, passes a >= PVCALLS_NR_RSP_PER_RING
test and indexes bedata->rsp[-1]. Declare req_id as u32 so a single
bound covers both ends.
A backend that sends an out-of-range req_id has violated the wire
protocol, so rather than silently dropping the response, log once and
stop trusting the backend: set bedata->disabled. The event handler then
ignores further responses, and the request paths that wait for a
response return -EIO instead of blocking forever. This mirrors the
fatal-error handling xen-netback uses (xenvif_fatal_tx_err()).
The pvcalls frontend currently trusts its backend, so this is not a
classic-Xen security issue, but it matters for hardening PV frontends
against malicious backends (confidential and disaggregated deployments). |

net/sched: act_pedit: fix TOCTOU heap OOB write in tc offload
There is a TOCTOU race condition in flower lockless approach between sizing
a flow_rule buffer and filling it.
zdi-disclosures@trendmicro.com reports:
The cls_flower classifier operates with TCF_PROTO_OPS_DOIT_UNLOCKED
(fl_change runs without RTNL), while RTM_NEWACTION holds RTNL, so the
independent locking domains make the race reachable in practice. KASAN
confirms:
BUG: KASAN: slab-out-of-bounds in tcf_pedit_offload_act_setup+0x81b/0x930
Write of size 4 at addr ffff888001f27520 by task poc-toctou/312
The buggy address is located 0 bytes to the right of
allocated 288-byte region [ffff888001f27400, ffff888001f27520)
(cache kmalloc-512)
Note: The result is a heap OOB write attacker-controlled content into the
adjacent slab object (requires CAP_NET_ADMIN).
The fix introduces reading tcfp_nkeys under act->tcfa_lock in all places
using a new tcf_pedit_nkeys_locked() which replaces the old tcf_pedit_nkeys().
Additionally we close the remaining TOCTOU window between the sizing read and
the fill reads by more careful accounting.
Rather than silently truncating the key count, which leads to incorrect
action semantics offloaded to hardware and secondary OOB writes if
the remaining capacity is zero or consumed by prior actions, we enforce
remaining capacity checks and return -ENOSPC if the required space exceeds
the remaining capacity. |

ocfs2: fix UBSAN array-index-out-of-bounds in ocfs2_sum_rightmost_rec
[BUG]
On-disk corruption setting l_next_free_rec to 0 in an inode's embedded
extent list triggers a UBSAN panic on the next write to that file.
[CAUSE]
ocfs2_sum_rightmost_rec() computes
i = le16_to_cpu(el->l_next_free_rec) - 1
and accesses el->l_recs[i] without validating i. When l_next_free_rec
is 0, i becomes -1; when l_next_free_rec exceeds l_count, i falls
past the end of the array. Either case violates the
__counted_by_le(l_count) annotation on l_recs[] and triggers UBSAN.
[FIX]
Validate the inode's embedded extent list when the inode is read, in
ocfs2_validate_inode_block(): l_count must be non-zero and no larger
than the inode block can hold, and l_next_free_rec must not exceed
l_count. A corrupt list is rejected at read time, before the b-tree
code can index l_recs[] out of bounds. |
| In the Linux kernel, the following vulnerability has been resolved:
nvmet-auth: reject short AUTH_RECEIVE buffers
nvmet_execute_auth_receive() trusts the AUTH_RECEIVE allocation length
after checking only that it is nonzero and matches the transfer length.
In the SUCCESS1 and FAILURE1/default states, that lets a remote NVMe-oF
initiator reach the fixed-size DH-HMAC-CHAP response builders with a
kmalloc() buffer shorter than the response, so nvmet_auth_success1() and
nvmet_auth_failure1() write past the allocation; both only WARN_ON the
short length and then format the message anyway.
Impact: A remote NVMe-oF initiator with access to an auth-enabled target
can trigger a 16-byte heap out-of-bounds write via a one-byte
AUTH_RECEIVE allocation length.
Compute the minimum response length for the current DH-HMAC-CHAP step in
nvmet_auth_receive_data_len() and report a zero data length when the
host-supplied allocation length is shorter, so the existing zero-length
check in nvmet_execute_auth_receive() rejects the command before any
builder runs. The SUCCESS1 minimum is sizeof(struct
nvmf_auth_dhchap_success1_data) plus the HMAC hash length, because the
response hash is written into the rval[] flexible-array tail, so the
minimum is state dependent rather than a flat sizeof. CHALLENGE keeps its
existing variable-length guard in nvmet_auth_challenge().
This is reachable only when in-band DH-HMAC-CHAP authentication is
configured on the target. |

dm-verity: fix buffer overflow in FEC calculation
There's a buffer overflow in dm-verity-fec:
if (neras && *neras <= v->fec->roots)
fio->erasures[(*neras)++] = i;
This allows *neras to reach roots + 1 (the post-increment pushes it past
roots). This value is then passed as no_eras to decode_rs8(). Inside the
RS decoder (lib/reed_solomon/decode_rs.c:113-121), the erasure locator
polynomial loop writes lambda[j] where j can reach nroots + 1 — one
element past the end of lambda[] (which is sized nroots + 1, valid
indices 0..nroots). The out-of-bounds write lands on syn[0], corrupting
the syndrome buffer. |

firmware: arm_ffa: Fix out-of-bound writes in ffa_setup_and_transmit()
Sashiko (locally) reports multiple out-of-bound issues in
ffa_setup_and_transmit:
1) Writing ep_mem_access->reserved can write out of bounds for FFA
versions < 1.2 as ffa_emad_size_get() returns 16 bytes in that case
while reserved has an offset of 24.
Instead of zeroing fields, memset the struct to zero first based on
the FFA version.
2) Make sure there is enough size to write constituents.
While at it, convert the only sizeof() in the driver that uses a
type instead of variable. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Check bounds on CRIU restore queue type and mqd size
We weren't checking whether the values provided in the private
data in kfd CRIU restore were within bounds.
For queue type, add a KFD_QUEUE_TYPE_MAX and ensure the provided
type is less than it.
For mqd_size, add new function mqd_size_from_queue_type and confirm
that the provided mqd_size matches expectations.

| luci-app-travelmate (and the travelmate package) contain a privilege-escalation flaw: a LuCI/rpcd session holding the luci-app-travelmate write ACL is granted config-wide UCI write access to the travelmate configuration. While the LuCI UI restricts the auto-login script picker to /etc/travelmate/*.login, this is only a frontend restriction. The backend travelmate service (running as root) reads the raw UCI 'script' and 'script_args' values and executes the configured path when the captive-portal auto-login branch (f_check() in travelmate-functions.sh) is reached. An attacker with delegated write permissions can set script to /bin/sh and script_args to attacker-controlled arguments, resulting in arbitrary command execution as root. Confirmed in luci-app-travelmate/travelmate 2.4.5-r3; travelmate 2.4.6-1 is also affected. Fixed in travelmate 2.4.6-2, which enforces the /etc/travelmate/*.login allowlist in the backend. |
