Description
Description
In the Linux kernel, the following vulnerability has been resolved:
misc: fastrpc: fix memory corruption on open
The probe session-duplication overflow check incremented the session
count also when there were no more available sessions so that memory
beyond the fixed-size slab-allocated session array could be corrupted in
fastrpc_session_alloc() on open().

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a memory corruption issue in the Linux kernel's fastrpc component. Specifically, when opening a session, the code incorrectly increments the session count even when no more sessions are available, leading to memory corruption beyond the fixed-size session array.
How can this vulnerability impact me? :
The memory corruption caused by this vulnerability could potentially lead to system instability, crashes, or exploitation by attackers to execute arbitrary code or escalate privileges.
