CVE-2026-23107

CVE-2026-23107 describes a Linux kernel issue in arm64/fpsimd where restoring a ZA (Streaming/SME) context could leave sve_state NULL if allocated late, causing a NULL pointer dereference when the kernel stores register state if TIF_SME is set. The root cause is that restore_za_context() failed t...

CVE-2026-23102 arm64/fpsimd: signal: Fix restoration of SVE context

In the Linux kernel, the following vulnerability has been resolved: arm64/fpsimd: signal: Fix restoration of SVE context When SME is supported, Restoring SVE signal context can go wrong in a few ways, including placing the task into an invalid state where the kernel may read from out-of-bounds...

kernel: denial of service in arch/powerpc/kernel/signal_32.c and arch/powerpc/kernel/signal_64.c via sigreturn() system call

A flaw was found in the PowerPc platform, where the kernel will panic if the transactional memory is disabled. An attacker could use this flaw to panic the system by constructing a signal context through the transactional memory MSR bits set...
