kernel: ipv4: fib: free fib_alias with kfree_rcu() on insert error path

A flaw was found in the Linux kernel's IPv4 forwarding information base FIB component. A local attacker with administrative network capabilities CAPNETADMIN could exploit a timing issue during route insertion and lookup operations. This could lead to a "use-after-free" vulnerability, where the...

kernel: ALSA: seq: close a re-opened queue timer in the destructor

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture sequencer component. An unprivileged local user with access to the sound device can exploit a timing window during the cleanup of a queue timer. This allows the user to re-open a timer that has already been closed,...

kernel: vfio/pci: clear vdev->msi_perm after freeing it on init failure

A flaw was found in the Linux kernel's vfio/pci component. During device initialization, a memory pointer is not properly cleared after being freed, leading to a use-after-free and double-free vulnerability. A local attacker could exploit this flaw to cause a system crash, resulting in a denial o...

kernel: fuse: re-lock request before returning from fuse_ref_folio()
