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...

evtchn: Race between FIFO expand and reset

ISSUE DESCRIPTION The EVTCHNOPexpandarray hypercall checks for whether FIFO event channels are enabled, but without holding the correct lock. It can race with EVTCHNOPreset, resulting in dereferencing a NULL pointer. IMPACT A malicious HVM guest x86 HVM or PVH, and ARM can crash Xen leading to a...

CVE-2026-64215

A flaw was found in the Linux kernel's drm/msm/a6xx component. This vulnerability occurs because the a8xxhfisendperftable function does not properly check the return value of a memory allocation call kzalloc. An attacker could potentially exploit this missing check to trigger a NULL pointer...
