Linux Kernel fastrpc Memory Corruption Vulnerability

A memory corruption vulnerability has been identified in the Linux kernel's fastrpc component. The issue arises during the session-duplication process, where the overflow check improperly increments the session count. This mismanagement allows for memory beyond the fixed-size, slab-allocated session array to be corrupted when a session is opened.

Impact

Exploitation of this vulnerability leads to memory corruption, which can potentially be exploited to execute arbitrary code or cause a denial-of-service condition.
