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: net: bridge: use a stable FDB dst
 snapshot in RCU readers Local FDB entries can be rewritten in place by `fdb_delete_local()`, which updates
 `f->dst` to another port or to `NULL` while keeping the entry alive. Several bridge RCU readers inspect
 `f->dst`, including `br_fdb_fillbuf()` through the `brforward_read()` sysfs path. These readers currently
 load `f->dst` multiple times and can therefore observe inconsistent values across the check and later
 dereference. In `br_fdb_fillbuf()`, this means a concurrent local-FDB update can change `f->dst` after the
 NULL check and before the `port_no` dereference, leading to a NULL-ptr-deref. Fix this by taking a single
 `READ_ONCE()` snapshot of `f->dst` in each affected RCU reader and using that snapshot for the rest of the
 access sequence. Also publish the in-place `f->dst` updates in `fdb_delete_local()` with `WRITE_ONCE()` so
 the readers and writer use matching access patterns. (CVE-2026-46086)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.613.40 or later.
