CVE-2020-35508

Published: 31 December 2020

A flaw possibility of race condition and incorrect initialization of the process id was found in the Linux kernel child/parent process identification handling while filtering signal handlers. A local attacker is able to abuse this flaw to bypass checks to send any signal to a privileged process.

From the Ubuntu Security Team

It was discovered that a race condition existed that caused the Linux kernel to not properly restrict exit signal delivery. A local attacker could possibly use this to send signals to arbitrary processes.

Notes

AuthorNote
mdeslaur
possibly Red Hat specific, but bug lists upstream
commits, needs investigation
sbeattie
The upstream commit is with respect to the race condition, not the improper initialization.
