{"id":"CVE-2026-89863","summary":"scsi: qla2xxx: edif: Fix NULL pointer deref in RX SA delete check","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: edif: Fix NULL pointer deref in RX SA delete check\n\nqla_chk_edif_rx_sa_delete_pending() obtains the SCSI command via\nGET_CMD_SP(sp) and immediately dereferences cmd-\u003esc_data_direction.\nThat command pointer can be NULL: the firmware may post a status\ncompletion for a command that has already been returned or aborted.  The\ncaller qla2x00_status_entry() acknowledges this on the very same status\npath, re-fetching GET_CMD_SP(sp) and bailing out with the \"Command\nalready returned\" message when it is NULL -- but that check runs only\nafter qla_chk_edif_rx_sa_delete_pending() has already dereferenced the\npointer, so a NULL cmd crashes the kernel in interrupt context.\n\nReturn early when cmd is NULL, before touching cmd-\u003esc_data_direction.","modified":"2026-09-18T03:48:33.604849578Z","published":"2026-09-16T10:31:34.377Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89863.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2191b0034a2f1307d421782e6eceddf8eec9e7f6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/75fd6d041c4a325ae37f4683e6678d3015988bb0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/94bfb61478bcb207d27f8cd24fd231421059519f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/96eb8a3fc9f7fe7ba32679fcf1d2fd7d251e7a8b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c20ee380ca59c5a8646750c4849969a815924e2e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/de0c8ef3b900c5e971c82ef38c6f5c22c5f3d8c1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e479e9b148456905d12711411484b94083c8ff58"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89863.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89863"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"dd30706e73b70d67e88fdaca688db7a3374fd5de"},{"fixed":"e479e9b148456905d12711411484b94083c8ff58"},{"fixed":"2191b0034a2f1307d421782e6eceddf8eec9e7f6"},{"fixed":"de0c8ef3b900c5e971c82ef38c6f5c22c5f3d8c1"},{"fixed":"96eb8a3fc9f7fe7ba32679fcf1d2fd7d251e7a8b"},{"fixed":"94bfb61478bcb207d27f8cd24fd231421059519f"},{"fixed":"75fd6d041c4a325ae37f4683e6678d3015988bb0"},{"fixed":"c20ee380ca59c5a8646750c4849969a815924e2e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89863.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.15.0"},{"fixed":"5.15.221"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.51"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89863.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
