Lifecycle Timeline
1DescriptionNVD
An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents.
AnalysisAI
An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through 4.18.11. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity.
Technical ContextAI
