CVSS v3.1 |
| ZBar commit 2ea2ca58 contains an undefined-behavior vulnerability in the Code 128 decode6() function. When processing specially crafted Code 128 input, decode_e() can return -1 for an invalid edge pattern, and decode6() subsequently left-shifts this negative signed value while constructing the edge signature. The operation invokes undefined behavior and can terminate trap-mode UBSan builds with SIGILL, resulting in denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv6: mcast: use copy-on-write RCU updates in ip6_mc_source()
pmc->sflist is read locklessly under rcu_read_lock() by
inet6_mc_check() during packet reception in the UDP and RAW
multicast receive paths.
ip6_mc_source() mutated psl->sl_addr and psl->sl_count in-place
when adding or removing a source filter. Additionally, when expanding
the filter buffer, newpsl was published via rcu_assign_pointer()
before writing the new source into the array.
Because 16-byte struct in6_addr writes are not atomic and array
shifting is not synchronized with RCU readers, concurrent readers in
inet6_mc_check() could read torn IPv6 addresses or observe
duplicated/missed source entries.
Fix this by switching ip6_mc_source() to copy-on-write RCU updates:
allocate and fully populate newpsl before publishing it via
rcu_assign_pointer(), and reclaim the old filter via kfree_rcu(),
matching ip6_mc_msfilter().
Also remove the now unused IP6_SFBLOCK macro. |

wifi: mac80211: mesh: release the channel if start fails
ieee80211_join_mesh() acquires a channel context and then calls
ieee80211_start_mesh(), which can fail. In that case, the chanctx
isn't released then interface removal will attempt to unassign it
after it's removed from the driver, hitting:
wlan0: Failed check-sdata-in-driver check, flags: 0x0

| In the Linux kernel, the following vulnerability has been resolved:
net: dsa: mxl862xx: disable the stats poll on teardown
mxl862xx_setup() arms the stats poll before mxl862xx_setup_mdio(), and
nothing stops it until dsa_register_switch() has returned an error to
mxl862xx_probe(). DSA frees the dsa_port list before it returns, so a
poll that fires once .setup or a later step of dsa_tree_setup() has
failed walks freed ports. On shutdown the user ports stay registered,
and the WORK_STOPPED flag test in mxl862xx_get_stats64() is not atomic
with the cancel in mxl862xx_shutdown(), so a re-arm that read the flag
before it was set queues the poll after cancel_delayed_work_sync() has
returned.
Arm the poll once .setup has succeeded and stop it from a .teardown op,
which DSA calls on unregister and after a failed registration, in both
cases before it frees the ports. Use disable_delayed_work_sync() there
and in shutdown(): it drains a running poll as the cancel did and turns
every later attempt to queue the work into a no-op, so the re-arm
cannot bring the poll back. remove() and the probe error path only set
WORK_STOPPED, which crc_err_work tests before it walks the ports. |
| A reachable assertion vulnerability exists in the Matter SDK (connectedhomeip) before 1.4.2, specifically within the Level Control cluster's periodic server tick logic. When a MoveToLevel command is sent and immediately followed by a write of OperationMode=2 (in the Pump Configuration and Control cluster), the server tick function violates the assertion `currentLevel < maxLevel`, resulting in a crash. This can be exploited remotely without authentication to cause denial of service. Affected versions include 1.3 and 1.4 (commit ab3d5ae). |
| In the Linux kernel, the following vulnerability has been resolved:
clk: scpi: bound-check DVFS index in scpi_dvfs_recalc_rate
dvfs_get_idx() may return an out-of-range index if the SCP firmware is
buggy or returns a stale value. Only negative indexes were rejected, so a
large index walked past info->opps and could treat garbage as a clock rate
(KASAN OOB / wrong frequency to consumers). The missing upper bound dates
back to the original SCPI clock driver.
Treat indexes >= opp count as invalid and return 0, same as idx < 0. |
| In the Linux kernel, the following vulnerability has been resolved:
xfrm: iptfs: fix runt reassembly panic from short inner tot_len
When the start of an inner packet is split across two outer packets
such that fewer than 4 bytes land at the end of the first one,
__input_process_payload() saves those bytes as a runt and skips the
iplen/iphlen validation performed for in-place packets. When the
continuation packet arrives, iptfs_reassem_cont() only requires the
declared inner length to be >= sizeof(ra_runt) (6) before allocating
the reassembly skb with that attacker-controlled length.
However, __iptfs_iphlen() always returns the fixed minimum IP header
size (20 for IPv4, 40 for IPv6), so for an inner IPv4 tot_len in
[6, 19] the header-completion copy writes past the declared packet
length, and the subsequent "ipremain -= copylen" underflows to ~4GB,
leaving the payload copy length bounded only by blkoff (up to 64KB).
At runtime the skb_put() tailroom check turns this into
skb_over_panic(), i.e. an unprivileged kernel panic (DoS), reachable
locally via userns+netns IPTFS SAs and remotely against IPTFS VPN
gateways when the decrypted outer skb is linear (e.g. AF_PACKET taps,
tun/tap delivery).
Align the runt path with the normal path by requiring the declared
inner length to cover at least the IP header size. This also subsumes
the previous >= sizeof(ra_runt) check, since the minimum IP header
is always larger than the runt buffer.
This issue was found by the autokbug dynamic kernel fuzzer at
Tencent Yunding Lab. |
| Smarty before 4.5.8 and 5.x before 5.8.5 contains a code injection vulnerability where the top-level nocache_hash is never restored during extends:/multi-component template inheritance, leaving it null. Attackers can supply assigned data containing a forged SmartyNocache marker that is copied verbatim into the regenerated PHP cache file, executing arbitrary PHP on include for remote code execution. |
| In the Linux kernel, the following vulnerability has been resolved:
phy: fsl-imx8mq-usb: fix typec switch leak on probe error path
If probe fails after imx95_usb_phy_get_tca() succeeds, the typec
switch leaks because the only cleanup path was in .remove(), which
never runs on probe failure.
Use devm_add_action_or_reset() so the switch is cleaned up on both
probe failure and driver removal. The imx95_usb_phy_put_tca() is no
longer needed, it will be removed in .remove() too. |

| In the Linux kernel, the following vulnerability has been resolved:
rds: ib: use rds_conn_drop() on protocol version mismatch
rds_ib_cm_connect_complete() runs from the RDMA-CM event handler with
conn->c_cm_lock held. When the peer negotiates a protocol version
older than RDS_PROTOCOL_COMPAT_VERSION, the handler calls
rds_conn_destroy(), which is only safe in the rmmod path: it
synchronously tears the connection down and flush_work()es the
shutdown work cp_down_w.
That shutdown work (rds_conn_shutdown()) needs cp_cm_lock, which is
the very lock the event handler still holds, so the flush never
completes: the two workers wait on each other and the RDS connection
workqueues stall for good.
All other RDMA-CM failure paths (REJECTED, CONNECT_ERROR,
DISCONNECTED) use rds_conn_drop(), which marks the connection
RDS_CONN_ERROR and schedules the shutdown work asynchronously. Use
it here as well. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: wilc1000: fix out-of-bounds read in P2P public action frames
wilc_wfi_p2p_rx() and mgmt_tx() start parsing a frame once
ieee80211_is_public_action() returns true. That helper only verifies the
frame is long enough for the action category field, that is
offsetofend(struct ieee80211_mgmt, u.action.category), 25 bytes. Both
functions then read the P2P public action header up to oui_subtype at
offset 30 and pass "size - ie_offset" to cfg80211_find_vendor_ie(), where
ie_offset is offsetof(struct ieee80211_mgmt, u) + sizeof(*d), i.e. 32.
A public action frame of 25 to 31 bytes passes the check but is shorter
than that 32 byte header, so oui_subtype can be read out of bounds, and
because the length is unsigned, "size - ie_offset" underflows to a value
close to 4 GiB. cfg80211_find_vendor_ie() takes an unsigned int length,
so even the size_t subtraction in mgmt_tx() is truncated to the same
value. It then walks far past the buffer searching for a vendor element
until it reaches unmapped memory.
In the receive path the frame arrives over the air and needs no
association, so a nearby unauthenticated device can crash the host while
it is in P2P listen. Reject frames shorter than the P2P public action
header in both paths before dereferencing it. |
| In the Linux kernel, the following vulnerability has been resolved:
IB/mlx4: Fix use-after-free on pkey sysfs registration failure
register_pkey_tree() ignores errors from register_one_pkey_tree() and
continues registering the remaining slaves. The per-slave error path has
already released the pkey parent kobjects, but their pointers remain
stored in the device. A later device cleanup therefore passes the stale
pointers to kobject_put(), causing a use-after-free.
Clear the parent pointers after releasing a failed slave tree and skip
unregistered trees during device cleanup. This preserves the existing
best-effort registration behavior while preventing a second cleanup of
the failed tree. |
| In the Linux kernel, the following vulnerability has been resolved:
arm64: hibernate: pass HVC_SET_VECTORS args to the resume hvc
swsusp_arch_suspend_exit() reinstalls the restored kernel's hyp stub
vectors with an hvc, but never passes the arguments. x0 is not set to
HVC_SET_VECTORS and x1 is not set to the vector address, so the stub
dispatch falls through and returns without writing vbar_el2. EL2 is
left pointing at the trans_pgd copy of the vectors, a page that
swsusp_free() releases right after resume.
Set the arguments up the same way __hyp_set_vectors() does.
Without this fix, Vladimir was able to trigger a hang when resuming from
hibernation with CONFIG_PAGE_POISONING=y and page_poison=on. |
| In the Linux kernel, the following vulnerability has been resolved:
pppoatm: ensure a writable skb header and linear data
In pppoatm_send(), LLC encapsulation checks whether there is sufficient
headroom for the 4-byte LLC header, but does not ensure that the skb header
is writable.
Normal transmit packets passing through ppp_start_xmit() have their header
unshared via skb_cow_head(). However, packets can also reach pppoatm_send()
via PPP channel bridging (PPPIOCBRIDGECHAN) without going through
ppp_start_xmit().
Use skb_cow_head() to ensure both sufficient headroom and a writable
header before pushing the LLC header.
While at it:
- Call pskb_may_pull(skb, 1) before inspecting skb->data[0] to prevent
out-of-bounds reads on zero-length or non-linear frames (e.g. from
bridging).
- Defer SC_COMP_PROT protocol compression until after pppoatm_may_send()
succeeds. This eliminates the temporary skb allocation on admission failure
and completely removes the fragile "undo" heuristic at the nospace label,
avoiding any risk of reading uninitialized headroom or performing an
unbalanced skb_push(). |
| A remote code execution vulnerability exists in Zimbra Collaboration (ZCS) before 10.1.20 when the optional zimbra-snmp package is installed and SNMP notifications are enabled. Due to improper sanitization of untrusted input during SNMP notification processing, an unauthenticated attacker can send specially crafted SMTP requests that may result in execution of arbitrary operating system commands as the Zimbra user. |
