CVE-2025-38607 (GCVE-0-2025-38607)

Vulnerability from cvelistv5 – Published: 2025-08-19 17:03 – Updated: 2025-09-29 05:54
VLAI?
Summary
In the Linux kernel, the following vulnerability has been resolved: bpf: handle jset (if a & b ...) as a jump in CFG computation BPF_JSET is a conditional jump and currently verifier.c:can_jump() does not know about that. This can lead to incorrect live registers and SCC computation. E.g. in the following example: 1: r0 = 1; 2: r2 = 2; 3: if r1 & 0x7 goto +1; 4: exit; 5: r0 = r2; 6: exit; W/o this fix insn_successors(3) will return only (4), a jump to (5) would be missed and r2 won't be marked as alive at (3).
Severity ?
