Echo: linux: security update to 6.1.170-1

medium Tenable Cloud Security Plugin ID 461776

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: soc: fsl: qbman: fix race condition in
qman_destroy_fq When QMAN_FQ_FLAG_DYNAMIC_FQID is set, there's a race condition between fq_table[fq->idx]
state and freeing/allocating from the pool and WARN_ON(fq_table[fq->idx]) in qman_create_fq() gets
triggered. Indeed, we can have: Thread A Thread B qman_destroy_fq() qman_create_fq() qman_release_fqid()
qman_shutdown_fq() gen_pool_free() -- At this point, the fqid is available again -- qman_alloc_fqid() --
so, we can get the just-freed fqid in thread B -- fq->fqid = fqid; fq->idx = fqid * 2;
WARN_ON(fq_table[fq->idx]); fq_table[fq->idx] = fq; fq_table[fq->idx] = NULL; And adding some logs between
qman_release_fqid() and fq_table[fq->idx] = NULL makes the WARN_ON() trigger a lot more. To prevent that,
ensure that fq_table[fq->idx] is set to NULL before gen_pool_free() is called by using smp_wmb().
(CVE-2026-23463)
