CVE-2024-41079 Open this link in a new tabHow to fix?
There is no fixed version for RHEL:8 perf.
NVD Description
Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
nvmet: always initialize cqe.result
The spec doesn't mandate that the first two double words (aka results) for the command queue entry need to be set to 0 when they are not used (not specified). Though, the target implemention returns 0 for TCP and FC but not for RDMA.
Let's make RDMA behave the same and thus explicitly initializing the result field. This prevents leaking any data from the stack.
