CVE-2024-50275

The CVE (CVE-2024-50275) affects the Linux kernel on arm64 with SVE traps. A race allows stale FPSIMD/SVE state to be reused across preemption, leading to SVE traps while TIF_SVE is set and potentially incorrect live state handling. The fix detaches from the saved CPU state when not live by calli...

CVE-2024-50275

In the Linux kernel, the following vulnerability has been resolved: arm64/sve: Discard stale CPU state when handling SVE traps The logic for handling SVE traps manipulates saved FPSIMD/SVE state incorrectly, and a race with preemption can result in a task having TIFSVE set and TIFFOREIGNFPSTATE...

CVE-2021-46984

CVE-2021-46984 : Linux kernel kyber driver had an out-of-bounds read due to a race between blk_mq_get_ctx() calls when a thread is preempted, causing ctx->index_hw[hctx->type] to differ from hctx. The fix passes the request_queue to kyber_bio_merge() (via ->bio_merge()) so Kyber can map ...
