CVE-2023-52978

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to the fixed version

Description A vulnerability in the Linux kernel has been resolved, which previously caused a kernel panic when probing an illegal position. This occurred when the kprobe's ebreak instruction broke the kernel's original code. The issue is related to the arch prepare kprobe function, where an arch check kprobe was added to prevent probing at an illegal position, such as the middle of an instruction.

Recommendations For Linux kernel versions prior to the fixed version, apply the patch that adds arch check kprobe in arch prepare kprobe to prevent kernel panic when probing an illegal position. As a temporary workaround, consider avoiding the use of kprobes that may probe illegal positions until a patch is available.
