kernel: x86/bugs: Enable IBPB flush on BPF JIT allocation

A flaw was found in the Linux kernel. This vulnerability involves an incomplete defense against Spectre-v2, a type of attack that can expose sensitive information by exploiting how modern processors predict future operations. Specifically, when the Berkeley Packet Filter BPF Just-In-Time JIT...

CVE-2026-92519

A flaw was found in the Linux kernel. When the BPF Just-In-Time JIT compiler processes subprograms, a memory leak can occur. If JIT compilation fails for a subprogram, the bpfjitfree function does not properly free the associated memory for the JIT context offsets array. This can lead to a gradua...

CVE-2026-97944

The Linux kernel contains a flaw in the x86/cfi implementation where the cfi_get_func_hash() function uses an incorrect hard-coded offset for the FineIBT hash. This mismatch occurred because the hash immediate moved from offset 7 to offset 5 during a preamble optimization. Consequently, the BPF J...
