Vulnerability from github – Published: 2025-06-18 12:30 – Updated: 2025-11-19 15:31

Details

In the Linux kernel, the following vulnerability has been resolved:

x86/kprobes: Update kcb status flag after singlestepping

Fix kprobes to update kcb (kprobes control block) status flag to KPROBE_HIT_SSDONE even if the kp->post_handler is not set.

This bug may cause a kernel panic if another INT3 user runs right after kprobes because kprobe_int3_handler() misunderstands the INT3 is kprobe's single stepping INT3.

Severity

5.5 (Medium)
