In the Linux kernel, the following vulnerability has been resolved: ceph: avoid putting the realm twice when decoding snaps fails When decoding the snaps fails it maybe leaving the 'first_realm' and 'realm' pointing to the same snaprealm memory.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.56%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
