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: nvmet-tcp: Fix potential UAF when
ddgst mismatch Shivam Kumar found via vulnerability testing: When data digest is enabled on an NVMe/TCP
connection and a digest mismatch occurs on a non-final H2C_DATA PDU during an R2T-based data transfer, the
digest error handler in nvmet_tcp_try_recv_ddgst() calls nvmet_req_uninit() — which performs
percpu_ref_put() on the submission queue — but does NOT mark the command as completed. It does not set
cqe->status, does not modify rbytes_done, and does not clear any flag. When the subsequent fatal error
triggers queue teardown, nvmet_tcp_uninit_data_in_cmds() iterates all commands, checks
nvmet_tcp_need_data_in() for each one, and finds that the already-uninited command still appears to need
data (because rbytes_done < transfer_len and cqe->status == 0). It therefore calls nvmet_req_uninit() a
second time on the same command — a double percpu_ref_put against a single percpu_ref_get.
(CVE-2026-64535)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.675.48 or later.
