Description OSIDB Bzimport 2025-06-18 12:04:54 UTC
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().
