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
| Author | Note |
|---|---|
| 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. |
