UBUNTU-CVE-2026-97528: High severity ubuntu/linux-hwe-edge vulnerability
In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Unlink NVMe unsol ctx before freeing on LS reject error qlanvmexmtlsrsp() obtains uctx, which was linked into fcport->unsolctxhead by qla2xxxprocesspurlsiocb() and is still linked when the NVMe transport calls back to transmit the LS response. On the error (out:) path the function frees uctx with kfree() but never removes it from the list. This leaves a freed node in fcport->unsolctxhead: the next listaddtail() for that fcport writes through the freed node, and a subsequent listdel() can corrupt the list or panic. Unlink uctx with listdel() before kfree() on the error path, matching the other free sites in qlanvmereleaselsrspcmdkref() and qla2xxxprocesspurlspkt(). qla2x00relsp() in the failure path only returns the SRB to its pool and does not invoke sp->putfn, so the out: path is the sole free and uctx is always still linked there.
