M17n-lib: null-pointer write in read_mtext_element() on malformed utf-8

A flaw was found in m17n-lib. An attacker could provide specially crafted or truncated UTF-8 input to trigger an unhandled null pointer dereference during text processing. This issue causes the application to crash unexpectedly, resulting in a Denial of Service (DoS).

Sssd: sssd: denial of service via crafted passkey kerberos authentication request

A flaw was found in sssd. A local attacker can trigger a Denial of Service (DoS) by sending a specially crafted Pluggable Authentication Module (PAM) request when passkey authentication is enabled. Due to a missing state validation check in passkey Kerberos handling, the PAM responder dereferences an uninitialized pointer and crashes. This failure disrupts authentication services on the host.

Sssd: sssd: denial of service via missing sid extension in certificate mapping

A flaw was found in sssd. A remote attacker can cause a denial of service (DoS) by submitting a certificate that lacks an expected Security Identifier (SID) extension. In deployments configured with SID-based certificate mapping rules, the service fails to verify the presence of the extension before processing it, causing the process to crash during authentication or lookup operations.

Xfig: fig2dev segmentation fault in read_arcobject

In xfig diagramming tool, a segmentation fault while running fig2dev allows an attacker to availability via local input manipulation via read_arcobject function.

Xfig: transfig: fig2dev segmentation fault vulnerability

A flaw was found in fig2dev. This vulnerability allows availability via local input manipulation via genge_itp_spline function.

Gnome-remote-desktop: freerdp: unauthenticated rdp packet causes segfault in freerdp leading to denial of service

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.

389-ds-base: null pointer dereference leads to denial of service

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.

Libtiff: null pointer dereference in tif_dirinfo.c

A null pointer dereference flaw was found in Libtiff via `tif_dirinfo.c`. This issue may allow an attacker to trigger memory allocation failures through certain means, such as restricting the heap space size or injecting faults, causing a segmentation fault. This can cause an application crash, eventually leading to a denial of service.

Libvirt: crash of virtinterfaced via virconnectlistinterfaces()

A flaw was found in libvirt. A refactor of the code fetching the list of interfaces for multiple APIs introduced a corner case on platforms where allocating 0 bytes of memory results in a NULL pointer. This corner case would lead to a NULL-pointer dereference and subsequent crash of virtinterfaced. This issue could allow clients connecting to the read-only socket to crash the virtinterfaced daemon.

Libsoup: null pointer dereference in client when server omits the "nonce" parameter in an unauthorized response with digest authentication

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.

Libsoup: null pointer deference on libsoup via /auth/soup-auth-digest.c through "soup_auth_digest_authenticate" on client when server omits the "realm" parameter in an unauthorized response with digest authentication

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.

Libsoup: null pointer dereference on libsoup through function "sniff_mp4" in soup-content-sniffer.c

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.

Gnuplot: gnuplot segmentation fault on x11_graphics

A flaw was found in gnuplot. The X11_graphics() function may lead to a segmentation fault and cause a system crash.

Gnuplot: gnuplot segmentation fault on canvas_text

A flaw was found in gnuplot. The CANVAS_text() function may lead to a segmentation fault and cause a system crash.

Gnuplot: gnuplot segmentation fault on xstrftime

A flaw was found in gnuplot. The xstrftime() function may lead to a segmentation fault, causing a system crash.

Gnuplot: gnuplot segmentation fault on getannotatestring

A flaw was found in gnuplot. The GetAnnotateString() function may lead to a segmentation fault and cause a system crash.

Gnuplot: gnuplot segmentation fault on plot3d_points

A flaw was found in gnuplot. The plot3d_points() function may lead to a segmentation fault and cause a system crash.

A null pointer dereference was addressed with improved validation. This issue is fixed in iOS 26.7.2 and iPadOS 26.7.2, iOS 27.2 and iPadOS 27.2, macOS Golden Gate 27.2, macOS Tahoe 26.7.2, tvOS 27.2, visionOS 27.2, watchOS 27.2. An attacker in physical proximity may be able to cause a denial-of-service.

An issue was discovered in the NPU driver in Samsung Mobile Processor Exynos 1280, 2200, 1380, 1480, 2400, 1580, 2500. There is a NULL Pointer Dereference of hdev in the __npu_vertex_bootup function.

Null Pointer Dereference Causes Unexpected System Termination in Apple Operating Systems

A null pointer dereference was addressed with improved input validation. This issue is fixed in iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Tahoe 26.7.2, tvOS 27, visionOS 27, watchOS 27. An app may be able to cause unexpected system termination.
