CVE-2026-72163

A flaw was found in the Linux kernel's OCFS2 component. A local user with write access to an OCFS2 filesystem could trigger a kernel panic by performing a direct write over unwritten extents. This occurs when the journal aborts during Direct I/O DIO completion, leading to a NULL pointer dereferen...

CVE-2026-72013

A flaw was found in the Linux kernel. Specifically, within the riscv architecture's machinekexecprepare function, a NULL pointer dereference can occur. This vulnerability arises when a NULL buffer is copied without proper validation during the kexec preparation process. An attacker could...

CVE-2026-72008

A flaw was found in the pmdomain: mediatek driver of the Linux kernel. This vulnerability occurs due to incorrect handling of Hardware Voter HWV type power domains during cleanup and power-on checks. Specifically, the driver might use inappropriate functions for checking power status and performi...

kernel: mm/slub: avoid accessing metadata when pointer is invalid in object_err()

A flaw was found in the Linux kernel’s SLUB memory allocator mm/slub. The function objecterr — used for debugging object metadata freelist pointer, redzone, etc. — can access invalid pointers when reporting corruption, leading to a crash. In some cases, due to freelist corruption e.g., detected b...

CVE-2026-74442

A flaw was found in the Linux kernel's drm/vmwgfx driver. This vulnerability occurs when the vmwvkmsinit function fails to initialize a workqueue, leaving a pointer as NULL. During module unload, the vmwvkmscleanup function attempts to destroy this NULL workqueue, leading to a kernel panic. A loc...

CVE-2026-74538

A flaw was found in the Linux kernel's Bluetooth ISO Isochronous Stream subsystem. A missing lock when accessing socket connection information within the isoconnectind function could lead to a null pointer dereference. This vulnerability could allow a local attacker to cause a system crash,...

CVE-2026-74445

A flaw was found in the Linux kernel's drm/vmwgfx component. A local attacker can trigger a null pointer dereference by sending a specially crafted command to the vmwcmddxbindquery function. This can lead to a kernel crash, resulting in a Denial of Service DoS for the affected system...

CVE-2026-74491

A flaw was found in the Linux kernel. A null pointer dereference vulnerability exists within the ofpcirangeparserone function.
