Veracode Vulnerability DatabaseVERACODE:19506Memory Corruption
EPSS
Percentile
36.5%
Linux kernel is vulnerable to memory corruption attacks. This occurs in the fs/timerfd.c file which allows a local user to cause a kernel list corruption or use-after-free via simultaneous operations with a file descriptor which leverage improper might_cancel queuing. An unprivileged local user could use this flaw to cause a denial of service on the system.
