Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue concerns the Linux kernel, where the function adjust jmp off() incorrectly used the insn->imm field for all overflow checks. This is incorrect because it should only be done for the BPF JMP32 | BPF JA case, not for the general jump instruction case. The fix involves using insn->off for overflow checks in the general case.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
