{"id":"CVE-2026-97528","summary":"scsi: qla2xxx: Unlink NVMe unsol ctx before freeing on LS reject error","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Unlink NVMe unsol ctx before freeing on LS reject error\n\nqla_nvme_xmt_ls_rsp() obtains uctx, which was linked into\nfcport-\u003eunsol_ctx_head by qla2xxx_process_purls_iocb() and is still linked\nwhen the NVMe transport calls back to transmit the LS response. On the\nerror (out:) path the function frees uctx with kfree() but never removes\nit from the list. This leaves a freed node in fcport-\u003eunsol_ctx_head: the\nnext list_add_tail() for that fcport writes through the freed node, and a\nsubsequent list_del() can corrupt the list or panic.\n\nUnlink uctx with list_del() before kfree() on the error path, matching the\nother free sites in qla_nvme_release_lsrsp_cmd_kref() and\nqla2xxx_process_purls_pkt(). qla2x00_rel_sp() in the failure path only\nreturns the SRB to its pool and does not invoke sp-\u003eput_fn, so the out:\npath is the sole free and uctx is always still linked there.","modified":"2026-09-26T03:48:29.025868207Z","published":"2026-09-25T10:21:30.130Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97528.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a95fc5f1c12bba1dbff72bd2611e7fad0758831b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c55d649a6cc246c3ccd5d118faea230c46b60f35"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e46160a5d4fa59bf4d5f3412b6b5cb79edb967dd"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97528.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97528"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"875386b98857822b77ac7f95bdf367b70af5b78c"},{"fixed":"a95fc5f1c12bba1dbff72bd2611e7fad0758831b"},{"fixed":"c55d649a6cc246c3ccd5d118faea230c46b60f35"},{"fixed":"e46160a5d4fa59bf4d5f3412b6b5cb79edb967dd"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97528.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.6.0"},{"fixed":"6.18.53"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97528.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
