Description
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.
Affected configurations
• linux linux kernel (>= 5.13 < 5.15.61)
• linux linux kernel (>= 5.16 < 5.18.18)
• linux linux kernel (>= 5.19 < 5.19.2)
