CVE-2026-98049

The Linux kernel contains a vulnerability where an arena 32-bit cmpxchg operation fails to perform a required zero extension. The root cause is that is_cmpxchg_insn() only matches BPF_ATOMIC, causing arena operations rewritten to BPF_PROBE_ATOMIC by bpf_convert_ctx_accesses() to miss the necessar...

CVE-2026-50185

A flaw was found in the cmov component of RustCrypto. The aarch64 implementations of Cmov and CmovEq incorrectly assume that high bits are zero-extended when loading values smaller than a register. This can lead to incorrect output when certain high bits are set in a Cmov selector or in the u16 a...
