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

Description A bug in the Linux kernel has been resolved, which could cause a kernel panic if another INT3 user runs right after kprobes. The issue arises because kprobe int3 handler() misunderstands the INT3 as kprobe's single stepping INT3. The fix involves updating the kcb (kprobes control block) status flag to KPROBE HIT SSDONE even if the kp->post handler is not set.

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