Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The Linux kernel contains a race condition within the qman destroy fq function in the soc: fsl: qbman component. This occurs when the QMAN FQ FLAG DYNAMIC FQID flag is set, specifically during the freeing and allocation of fqids. A race condition can occur between the fq table state and the pool allocation/deallocation, potentially triggering a WARN ON() error in qman create fq(). The issue arises when a freed fqid is reallocated to a different thread before the original thread completes its cleanup, leading to inconsistencies in the fq table.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
