| SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate. CertChecker now returns an error instead of panicking when these callbacks are nil. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: PCM: Fix wait queue list corruption in snd_pcm_drain() on linked streams
snd_pcm_drain() uses init_waitqueue_entry which does not clear
entry.prev/next, and add_wait_queue with a conditional
remove_wait_queue that is skipped when to_check is no longer
in the group after concurrent UNLINK. The orphaned wait entry
remains on the unlinked substream sleep queue. On the next
drain iteration, add_wait_queue adds the entry to a new queue
while still linked on the old one, corrupting both lists. A
subsequent wake_up dereferences NULL at the func pointer
(mapped from the spinlock at offset 0 of the misinterpreted
wait_queue_head_t), causing a kernel panic.
Replace init_waitqueue_entry/add_wait_queue/conditional
remove_wait_queue with init_wait_entry/prepare_to_wait/
finish_wait. init_wait_entry clears prev/next via
INIT_LIST_HEAD on each iteration and sets
autoremove_wake_function which auto-removes the entry on
wake-up. finish_wait safely handles both the already-removed
and still-queued cases. |

Kernel panic - not syncing: Fatal exception
[ Analysis ]
We believe that we have found a concurrency bug in the `fs/jfs` module
that results in a null pointer dereference. There is a closely related
issue which has been fixed:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d6c1b3599b2feb5c7291f5ac3a36e5fa7cedb234
... but, unfortunately, the accepted patch appears to still be
susceptible to a null pointer dereference under some interleavings.
To trigger the bug, we think that `JFS_SBI(ipbmap->i_sb)->bmap` is set
to NULL in `dbFreeBits` and then dereferenced in `jfs_ioc_trim`. This
bug manifests quite rarely under normal circumstances, but is
triggereable from a syz-program. |
| ccoap 77f55c4b466e99327c24ace8a2913d3ba7e2ccd5 contains a null pointer dereference vulnerability in the coap_dump_msg() function when processing COAP messages containing options with zero length. |
| ccoap 77f55c4b466e99327c24ace8a2913d3ba7e2ccd5 contains a null pointer dereference vulnerability in the coap_server_handle_session() function when processing COAP messages containing URI_PATH options with NULL data pointers. When the server searches for a URI_PATH option matching the string "separate", it directly calls strncmp() on option_list[i].data without checking if the pointer is NULL. This causes a segmentation fault when the option's data field is NULL. |
| PLANET GS-4210-16P2S V3 firmware before 3.441b260626 contains authenticated stack buffer overflow and null pointer dereference vulnerabilities in /cgi-bin/dispatcher.cgi. The web_radiusSrv*_post family of handlers copies the radKey, radKey_0, radDftParamKey, radName, and radIp POST parameters into fixed-size stack buffers without length validation, and additionally dereferences radName and radIp without verifying their presence in the request. A remote authenticated attacker can send crafted requests to crash the CGI process or web management service, resulting in denial of service. |
| PLANET GS-4210-16P2S V3 firmware before 3.441b260626 contains an authenticated null pointer dereference vulnerability in /cgi-bin/dispatcher.cgi. The web_poe_alive_rmtip_post handler dereferences the rmtIP parameter without verifying its presence. A remote authenticated attacker can send a crafted request omitting the rmtIP parameter to cause the CGI process to dereference a null pointer and crash, resulting in denial of service of the web management interface. |
| Nokogiri before 1.13.9 (CRuby implementation using packaged libraries) bundles libxml2 v2.9.14, which is affected by CVE-2022-40304 (data corruption / double-free from an entity reference cycle when entity content is allocated from a dict) and CVE-2022-40303 (integer overflows when parsing with XML_PARSE_HUGE). Nokogiri 1.13.9 upgrades the packaged libxml2 to v2.10.3 to address these issues. Processing crafted XML input may lead to denial of service or memory corruption. (The advisory also references CVE-2022-2309, a NULL pointer dereference via iterwalk/canonicalize, which maintainers determined does not affect Nokogiri users.) |
| Nokogiri before 1.14.3 (CRuby implementation only, when using the packaged libxml2) bundles libxml2 v2.10.3, which is vulnerable to NULL pointer dereferences in XML Schema processing (xmlSchemaFixupComplexType, CVE-2023-28484, and xmlSchemaCheckCOSSTDerivedOK). An attacker who supplies a crafted/malformed XML schema can cause libxml2 to dereference a NULL pointer and potentially segfault, resulting in a denial of service. Nokogiri 1.14.3 upgrades the packaged libxml2 to v2.10.4 to resolve these issues. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: picolcd: prevent NULL pointer dereference in picolcd_send_and_wait()
In picolcd_send_and_wait(), an integer overflow of the signed loop counter
'k' can theoretically lead to a NULL pointer dereference of 'raw_data'.
If the loop executes more than INT_MAX times, 'k' becomes negative,
making the condition 'k < size' true even when 'size' is 0.
Change the type of 'k' to 'unsigned int' to prevent the overflow and
eliminate the out-of-bounds access.
Found by Linux Verification Center (linuxtesting.org) with the Svace static
analysis tool.

| In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: enforce cursor size limits for MOB cursors
vmw_cursor_plane_atomic_check() bounds cursor width and height only
on the legacy update path; the SVGA_CAP2_CURSOR_MOB path -- the
default on modern hosts -- accepts any size. When the requested size
exceeds SVGA_REG_CURSOR_MAX_DIMENSION or SVGA_REG_MOB_MAX_SIZE,
vmw_cursor_mob_get() returns -EINVAL and leaves vps->cursor.mob NULL.
Its return value is then discarded in vmw_cursor_plane_prepare_fb(),
so the subsequent vmw_cursor_update_mob() calls
vmw_bo_map_and_cache(NULL) and oopses inside
vmw_bo_map_and_cache_size() on the tbo.base.size load.
Reachable from any DRM master via DRM_IOCTL_MODE_CURSOR2 with a
sufficiently large width or height (e.g. cursor_max_dim + 1).
Reject oversized cursors in atomic_check for both MOB-backed cursor
update types. The MOB byte-size limit only applies to the
SVGA_CAP2_CURSOR_MOB path (vmw_cursor_mob_size() returns 0 for
GB_ONLY); compute the required MOB size in 64-bit to avoid overflow
when very large dimensions are requested.
In prepare_fb only call vmw_cursor_mob_get()/_map() for
VMW_CURSOR_UPDATE_MOB -- the GB_ONLY path uses bo->map.virtual
directly and would otherwise be silently downgraded to NONE on hosts
without SVGA_CAP2_CURSOR_MOB (where vmw_cursor_mob_get() always
returns -EINVAL). Degrade the update to NONE if vmw_cursor_mob_get()
or vmw_cursor_mob_map() fails so the update path does not run with a
NULL backing MOB. |
| CMS protocol dissector crash in 4.6.0 to 4.6.7 and 4.4.0 to 4.4.18 allows denial of service |
| A vulnerability was identified in Open5GS up to 2.7.7. This issue affects some unknown processing of the file src/amf/namf-handler.c of the component Transfer Endpoint. Such manipulation leads to null pointer dereference. The attack can be launched remotely. Upgrading to version 2.8.0 is capable of addressing this issue. The name of the patch is abf8a836564b966b5141110fc25ed413c4f17522. Upgrading the affected component is advised. |
