In the Linux kernel, the following vulnerability has been resolved: af_packet: avoid erroring out after sock_init_data() in packet_create() After sock_init_data() the allocated sk object is attached to the provided sock object. On error, packet_create() frees the sk object leaving the dangling pointer in the sock object on return. Some other code may try to use this pointer and cause use-after-free.

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:0236-1 advisory.

    The SUSE Linux Enterprise 12 SP5 kernel was updated to receive various security bugfixes.
