| In the Linux kernel, the following vulnerability has been resolved:
mm/damon/lru_sort: handle ctx allocation failure
DAMON_LRU_SORT allocates the damon_ctx object for its kdamond in its init
function. damon_lru_sort_enabled_store() wrongly assumes the allocation
will always succeed once tried. If the damon_ctx allocation was failed,
therefore, code execution reaches to damon_commit_ctx() while 'ctx' is
NULL. As a result, it dereferences the NULL 'ctx' pointer. Avoid the
NULL dereference by returning -ENOMEM if 'ctx' is NULL. |
| JavaScript::Minifier::XS versions before 0.16 for Perl crash with a NULL pointer dereference when the first meaningful token of the input is a slash.
The regexp versus division disambiguator in JsTokenizeString (XS.xs) inspects the previous token's last byte to choose between a regexp literal and a division operator. When a slash is the first meaningful token, with the start of input or only whitespace and comments before it, there is no valid preceding token: the walk back over whitespace and comment nodes runs off the head of the node list to NULL, and the byte lookup reads through a NULL contents pointer at an underflowed length index. The following identifier check dereferences the same NULL pointer.
The crash is reachable through the public minify() API, so input as small as a single slash byte crashes the calling process. A service that minifies untrusted or third-party JavaScript can be crashed by a remote request, causing denial of service. |
| Woodpecker before 3.15.0 registers the /api/orgs/lookup/*org_full_name endpoint without authentication middleware, and the LookupOrg handler unconditionally dereferences the session user (user.ForgeID, via ForgeFromUser) when selecting the forge to query. For an unauthenticated request session.User returns nil, so any unauthenticated HTTP request triggers a NULL pointer dereference in the handler. The panic is recovered by gin recovery middleware and the server continues serving (returning HTTP 500), but each request writes a multi-line panic stack trace to the error log. A low-bandwidth unauthenticated attacker can repeatedly probe the endpoint to flood the logs (about 37 lines per request), inflating disk usage and downstream log-ingestion cost and burying legitimate log events. |
| A flaw was found in the FreeRDP used by Anaconda's remote install feature, where a crafted RDP packet could trigger a segmentation fault. This issue causes the service to crash and remain defunct, resulting in a denial of service. It occurs pre-boot and is likely due to a NULL pointer dereference. Rebooting is required to recover the system. |
| A denial-of-service vulnerability has been identified in the libsoup HTTP client library. This flaw can be triggered when a libsoup client receives a 401 (Unauthorized) HTTP response containing a specifically crafted domain parameter within the WWW-Authenticate header. Processing this malformed header can lead to a crash of the client application using libsoup. An attacker could exploit this by setting up a malicious HTTP server. If a user's application using the vulnerable libsoup library connects to this malicious server, it could result in a denial-of-service. Successful exploitation requires tricking a user's client application into connecting to the attacker's malicious server. |
| glib-networking's OpenSSL backend fails to properly check the return value of memory allocation routines. An out of memory condition could potentially result in writing to an invalid memory location. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/ras: Fix NULL deref in ras_core_get_utc_second_timestamp()
ras_core_get_utc_second_timestamp() retrieves the current UTC timestamp
(in seconds since the Unix epoch) through a platform-specific RAS system
callback and is used for timestamping RAS error events.
The function checks ras_core in the conditional statement before calling
the sys_fn callback. However, when the condition fails, the function
prints an error message using ras_core->dev.
If ras_core is NULL, this can lead to a potential NULL pointer
dereference when accessing ras_core->dev.
Add an early NULL check for ras_core at the beginning of the function
and return 0 when the pointer is not valid. This prevents the
dereference and makes the control flow clearer. |
| In xfig diagramming tool, a segmentation fault while running fig2dev allows an attacker to availability via local input manipulation via read_arcobject function. |
| A flaw was found in fig2dev. This vulnerability allows availability via local input manipulation via genge_itp_spline function. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/ras: Fix NULL deref in ras_core_ras_interrupt_detected()
Fixes a NULL pointer dereference when ras_core is NULL and ras_core->dev
is accessed in the error path.

| A flaw was found in libssh, a library that implements the SSH protocol. When calculating the session ID during the key exchange (KEX) process, an allocation failure in cryptographic functions may lead to a NULL pointer dereference. This issue can cause the client or server to crash. |
| A NULL pointer dereference vulnerability has been reported to affect several QNAP operating system versions. If a remote attacker gains an administrator account, they can then exploit the vulnerability to launch a denial-of-service (DoS) attack.
We have already fixed the vulnerability in the following versions:
QTS 5.2.9.3492 build 20260507 and later
QuTS hero h5.2.9.3499 build 20260514 and later
QuTS hero h5.3.4.3500 build 20260520 and later
QuTS hero h6.0.0.3459 build 20260409 and later |
| A NULL pointer dereference flaw was found in the GnuTLS software in _gnutls_figure_common_ciphersuite(). |
| A flaw was found in libsoup, where SoupAuthDigest is vulnerable to a NULL pointer dereference. The HTTP server may cause the libsoup client to crash. |
| A flaw was found in libsoup. SoupContentSniffer may be vulnerable to a NULL pointer dereference in the sniff_mp4 function. The HTTP server may cause the libsoup client to crash. |
| A flaw was found in libsoup, where soup_auth_digest_authenticate() is vulnerable to a NULL pointer dereference. This issue may cause the libsoup client to crash. |
| A flaw was found in the 389-ds-base LDAP Server. This issue occurs when issuing a Modify DN LDAP operation through the ldap protocol, when the function return value is not tested and a NULL pointer is dereferenced. If a privileged user performs a ldap MODDN operation after a failed operation, it could lead to a Denial of Service (DoS) or system crash. |
| A flaw was found in libsoup, where the soup_message_headers_get_content_disposition() function is vulnerable to a NULL pointer dereference. This flaw allows a malicious HTTP peer to crash a libsoup client or server that uses this function. |
| An unauthenticated
NULL pointer dereference vulnerability exists in IEEE8021x_upload.cgi in GeoVision
GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by
improper validation of multipart upload headers when processing
certificate-related upload fields. A remote attacker may exploit this
vulnerability by sending a malformed multipart request, causing the affected
CGI process to crash and resulting in a denial of service. |
| An unauthenticated
NULL pointer dereference vulnerability exists in the HTTP request parsing logic
of multiple CGI components in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and
earlier. The vulnerability is caused by improper validation of required HTTP
request metadata before it is used by the affected components. A remote attacker
may exploit this vulnerability by sending a specially crafted HTTP request,
causing the affected process to crash and resulting in a denial of service. |
