medium Tenable Self-Hosted Container Security Plugin ID 465920

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: nfs: handle failure of
nfs_get_lock_context in unlock path When memory is insufficient, the allocation of nfs_lock_context in
nfs_get_lock_context() fails and returns -ENOMEM. If we mistakenly treat an nfs4_unlockdata structure
(whose l_ctx member has been set to -ENOMEM) as valid and proceed to execute rpc_run_task(), this will
trigger a NULL pointer dereference in nfs4_locku_prepare. For example: BUG: kernel NULL pointer
dereference, address: 000000000000000c PGD 0 P4D 0 Oops: Oops: 0000 [#1] SMP PTI CPU: 15 UID: 0 PID: 12
