Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw where the
perf subsystem attempts to access user space memory during address space teardown in the do exit() function, potentially leading to a crash. This issue occurs when perf tries to perform a user stack sample while in exit mmap()'s tlb finish mmu() function. The fix involves reordering operations to stop perf before tearing down the user space memory map and hardening PERF SAMPLE CALLCHAIN and PERF SAMPLE STACK USER to abort when the current task does not have a memory map.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
