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: veth: fix NAPI leak in XDP enable
error path During XDP enablement in veth, if xdp_rxq_info_reg() or xdp_rxq_info_reg_mem_model() fails, the
driver rolls back the changes. However, the rollback loop: for (i--; i >= start; i--) { decrements the
loop index 'i' before the first iteration. This correctly skips unregistering the rxq for the failed index
'i' (as registration failed or was already cleaned up), but it also erroneously skips calling
netif_napi_deli() for rq[i].xdp_napi. Since netif_napi_add() was already called for index 'i', this leaves
a dangling napi_struct in the device's napi_list. When the veth device is later destroyed, the freed queue
memory (which contains the leaked NAPI structure) can be reused. The subsequent device teardown iterates
the NAPI list and corrupts the reallocated memory, leading to UAF. Fix this by explicitly deleting the
NAPI association for the failed index 'i' before rolling back the successfully configured queues.
(CVE-2026-80613)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.731.2 or later.
