Description OSIDB Bzimport 2024-07-29 16:26:21 UTC

In the Linux kernel, the following vulnerability has been resolved:

bpf: Take return from set_memory_ro() into account with bpf_prog_lock_ro()

set_memory_ro() can fail, leaving memory unprotected.

Check its return and take it into account as an error.
