In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix cleanup null-ptr deref on encap lock During module is unloaded while a peer tc flow is still offloaded, first the peer uplink rep profile is changed to a nic profile, and so neigh encap lock is destroyed. Next during unload, the VF reps netdevs are unregistered which causes the original non-peer tc flow to be deleted, which deletes the peer flow. The peer flow deletion detaches the encap entry and try to take the already destroyed encap lock, causing the below trace. Fix this by clearing peer flows during tc esw

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.

Executive

CVE-2023-53105 is a none public vulnerability record for Linux Linux. It is not currently listed in the CISA Known Exploited catalog. Check the linked vendor or CERT advisories for patch status. This summary is a catalog interpretation of the ingested metadata and cites the original advisories below.

System administrator

Identify whether Linux Linux is in your estate, then compare installed versions with the affected ranges. Affected packages or ranges on record: Linux Linux 04de7dda7394fa9c2b0fc9cec65661d9b4f0d04d <c9668f0b1d28570327dbba189f2c61f6f9e43ae7 (04de7dda7394fa9c2b0fc9cec65661d9b4f0d04d <c9668f0b1d28570327dbba189f2c61f6f9e43ae7). Check the linked vendor or CERT advisories for patch status. Prefer the vendor or distribution advisory linked in Sources before changing production systems. This is a catalog interpretation, not a runbook.
