CVE-2026-64245
A flaw was found in the Linux kernel's framebuffer device fbdev subsystem. Specifically, within the fbfindmode function, a use-after-free UAF vulnerability exists. This occurs because a memory buffer is released while still being referenced, potentially allowing an attacker to access or manipulat...
CVE-2026-64233
A flaw was found in the Linux kernel's USB Video Class UVC gadget driver. A privileged local user can exploit a race condition during the binding of a UVC function by concurrently removing an extension subdirectory. This can lead to a use-after-free vulnerability, potentially causing system...
CVE-2026-64225
A flaw was found in the Linux kernel's octeontx2-af: CGX component. This vulnerability arises from an out-of-bounds array access. Specifically, the RESPLINKSTATSPEED function can produce an index value that exceeds the allocated size of the cgxspeedmbps array, leading to memory corruption. This...
CVE-2026-64210
A flaw was found in the Linux kernel's mlx5e driver, which manages Mellanox network adapters. This vulnerability occurs during network processing when CPU core assignments change, leading to a race condition where critical data structures ICOSQ - Interrupt Coalescing Send Queue can be updated...
CVE-2026-64236
A flaw was found in the i2c davinci driver of the Linux kernel. When the 'clock-frequency' property is missing from the device tree, the driver's fallback mechanism can lead to a division-by-zero error. This vulnerability can be triggered by a local attacker providing a malformed device tree,...
CVE-2026-64239
A flaw was found in the Linux kernel's Data Access Monitor DAMON system file system sysfs component. A local user could exploit a timing issue during the refresh of DAMON region directories, leading to a use-after-free vulnerability. This could result in memory corruption, potentially causing...
CVE-2026-64253
A flaw was found in the Linux kernel. The copyprocess function, responsible for creating new processes, incorrectly inherits a flag PFBLOCKTS from the parent process while simultaneously setting a related pointer current-plug to null in the child process. This inconsistency can lead to the kernel...
