CVE-2026-97944 x86/cfi: Fix FineIBT hash offset in cfi_get_func_hash()

In the Linux kernel, the following vulnerability has been resolved: x86/cfi: Fix FineIBT hash offset in cfigetfunchash The switch of the FineIBT preamble from "subl $hash, %r10d" to the shorter "subl $hash, %eax" moved the hash immediate from offset 7 to offset 5 of the preamble...

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...
