CVE-2026-93256

A flaw was found in the Linux kernel. During the hibernation resume process on ARM64 systems, the kernel fails to properly mask processor exceptions before restoring the suspended system state. A local user could encounter or trigger an unhandled hardware exception while the system is in this...

CVE-2026-93255

A flaw was found in the Linux kernel's Btrfs file system. A race condition occurs between background read I/O completion and extent buffer cache invalidation during unmount operations because read status flags are cleared outside of the reference count lock. A local user performing file system...

CVE-2026-93244

A flaw was found in the Linux kernel's simpledrm driver. The driver fails to properly validate the computed display buffer stride, the byte width of a row of pixels, against the maximum integer limit. A local user could exploit this flaw to trigger calculation errors, leading to a kernel crash an...

CVE-2026-93248

A flaw was found in the Linux kernel's drm/xe graphics driver. When a graphics device becomes unresponsive wedged and execution queues are terminated, the driver fails to retain the wedged status during cleanup. A local user could exploit this flaw during driver unbinding to trigger an unexpected...

CVE-2026-93242

A flaw was found in the Linux kernel's qla2xxx Fibre Channel driver. When handling multi-entry response packets, an off-by-one counting error causes the driver to consume an extra entry from the response queue. This issue can cause legitimate firmware responses to be prematurely marked as process...

CVE-2026-93243

A flaw was found in the Linux kernel's secret memory secretmem subsystem. A local user can bypass locked memory resource limits by repeatedly mapping and unmapping secret memory ranges. Because the kernel fails to properly track these unevictable memory pages against user limits, an unprivileged...

CVE-2026-93241

A flaw was found in the Linux kernel. When the out-of-memory OOM killer terminates a multi-threaded process and asynchronous memory cleanup cannot complete, exiting threads continue to invoke memory reclamation and serialize behind an internal lock. A local user can exploit this vulnerability by...

CVE-2026-93240

A flaw was found in the Linux kernel's memory control group memcg subsystem. A local user with permissions to configure memory limits can cause a Denial of Service DoS by triggering memory reclamation under legacy memory soft limits. When the kernel's background memory reclamation process manages...

CVE-2026-93234

A flaw was found in the Linux kernel's Generic USB Display GUD driver. When reading television mode names from an attached device, the driver does not verify that the returned data contains a terminating null byte within its fixed-size buffer. A local attacker could attach a crafted device to cau...

CVE-2026-93232

A flaw was found in the Linux kernel's HugeTLB huge page memory management subsystem. During system startup, an uninitialized memory dereference occurs when HugeTLB Vmemmap Optimization HVO is enabled on a kernel compiled with virtual memory debugging options. A local user able to configure or...

CVE-2026-93231

A flaw was found in the Linux kernel's lockd subsystem. A local privileged user can cause a Denial of Service DoS due to reversed function arguments when releasing locks by IP address. This issue causes the kernel to misinterpret memory structures, leading to invalid memory reads and preventing...

CVE-2026-93229

A flaw was found in the Linux kernel's Network File System daemon nfsd. A local user can cause a Denial of Service DoS or observe inconsistent kernel data on systems with weakly-ordered processor architectures. This issue occurs due to a missing read memory barrier in the Remote Procedure Call RP...

CVE-2026-93227

A flaw was found in the Linux kernel. This vulnerability allows a local user with control over boot parameters, or systems with specific memory alignments, to cause a Denial of Service DoS through a kernel panic. During early system boot with deferred memory initialization enabled, improper...

CVE-2026-93230

A flaw was found in the Linux kernel. This issue may allow a local user to cause a Denial of Service DoS due to an improper initialization sequence in the HugeTLB Huge Translation Lookaside Buffer memory subsystem. During system startup, gigantic huge page memory structures can be inspected befor...

CVE-2026-93226

A flaw was found in the Linux kernel's IPv6 networking subsystem. A race condition occurs when reading route exception lists without proper synchronization against concurrent route updates. A local user can trigger this flaw by querying network routing tables during simultaneous route updates,...

CVE-2026-93222

A flaw was found in the Linux kernel's signal handling subsystem. When dispatching signals to a group of processes across different namespaces, the kernel modified shared signal metadata in place rather than copying it for each recipient. A local user could exploit this behavior to cause recipien...

CVE-2026-93217

A flaw was found in the Linux kernel's memory management subsystem. A race condition can occur when an HMM-based Graphics Processing Unit GPU driver interacts with madviseMADVCOLD or MADVPAGEOUT operations. This can lead to a kernel panic, effectively causing a Denial of Service DoS on the affect...

CVE-2026-93216

A flaw was found in the Linux kernel. A Time-of-check to time-of-use TOCTOU vulnerability exists in the printpageownermemcg function, where page-memcgdata is read multiple times without proper locking. If a memory page is concurrently freed and reallocated between these reads, it can trigger...

CVE-2026-93213

A flaw was found in the Linux kernel. An out-of-bounds read vulnerability exists in the ofaliasscan function's stem parser. This issue occurs because the parser checks for a digit before verifying if it's within the valid memory bounds, potentially allowing it to read one byte before the intended...
