- Summary
- x86/kprobes: Update kcb status flag after singlestepping
- 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 KPROBEHITSSDONE 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 kprobeint3handler() misunderstands the INT3 is kprobe's single stepping INT3.
