The vulnerable path is reached entirely from firmware-delivered link events.\nUI:N - No victim action is needed \u2014 the crash follows automatically from the link/session state change and the subsequent teardown once the flush has failed.\nS:U - The stale-pointer access, memory corruption, and crash are all confined to the host kernel; no security authority or virtualization boundary is crossed.\nC:H - The driver acts on a `scsi_cmnd` the midlayer has already reclaimed and may have reused, and on a freed `fc_port_t` still referenced by outstanding SRBs \u2014 a stale-pointer/UAF-class condition on heap objects whose contents an attacker can shape via I/O patterns, and `scsi_dma_unmap()` on a reused SGL triggers swiotlb copy-back into the wrong pages.\nI:H - The same primitive gives writes: unmapping an in-flight scatter-gather list lets the HBA DMA into pages the kernel has since freed and reallocated, and `qla2x00_sp_compl()` calls `scsi_done()` on a recycled request, corrupting another command's result and double-completing it in the block layer.\nA:H - The reported failure is a kernel NULL pointer dereference oops while DMA-unmapping the stale command's SGL, taking down the storage host; the fix additionally has to force a full chip reset to recover."}]}], "affected": [{"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "726b85487067d7f5b23495bc33c484b8517c4074", "lessThan": "b73377124f56d2fec154737c2f8d2e839c237d5a", "versionType": "git"}, {"status": "affected", "version": "726b85487067d7f5b23495bc33c484b8517c4074", "lessThan": "d7a68eee87b05d4e29419e6f151aef99314970a9", "versionType": "git"}, {"status": "affected", "version": "726b85487067d7f5b23495bc33c484b8517c4074", "lessThan": "67b2d35853c2da25a8ca1c4190a5e96d3083c2ac", "versionType": "git"}, {"status": "affected", "version": "726b85487067d7f5b23495bc33c484b8517c4074", "lessThan": "a859f6a8f4234b8ef62862bf7a92f1af5f8cd47a", "versionType": "git"}, {"status": "affected", "version": "726b85487067d7f5b23495bc33c484b8517c4074", "lessThan": "09c0ac18cac206ed1218b1fe6c1a0918e5ea9211", "versionType": "git"}, {"status": "affected", "version": "726b85487067d7f5b23495bc33c484b8517c4074", "lessThan": "8de1584ec4fe0ebea33c273036e7e0a05e65c81d", "versionType": "git"}, {"status": "affected", "version": "726b85487067d7f5b23495bc33c484b8517c4074", "lessThan": "8f0d32004e3a572bb77e6c11c2797c87f8c9703d", "versionType": "git"}, {"status": "affected", "version": "726b85487067d7f5b23495bc33c484b8517c4074", "lessThan": "ec7587eef003cab15a13446d67c3adb88146a150", "versionType": "git"}, {"status": "affected", "version": "726b85487067d7f5b23495bc33c484b8517c4074", "lessThan": "a27d4d0e7de305def8a5098a614053be208d1aa1", "versionType": "git"}], "programFiles": ["drivers/scsi/qla2xxx/qla_target.c"], "defaultStatus": "unaffected"}, {"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "4.11"}, {"status": "unaffected", "version": "0", "lessThan": "4.11", "versionType": "semver"}, {"status": "unaffected", "version": "4.19.312", "versionType": "semver", "lessThanOrEqual": "4.19.*"}, {"status": "unaffected", "version": "5.4.274", "versionType": "semver", "lessThanOrEqual": "5.4.*"}, {"status": "unaffected", "version": "5.10.215", "versionType": "semver", "lessThanOrEqual": "5.10.*"}, {"status": "unaffected", "version": "5.15.154", "versionType": "semver", "lessThanOrEqual": "5.15.*"}, {"status": "unaffected", "version": "6.1.84", "versionType": "semver", "lessThanOrEqual": "6.1.*"}, {"status": "unaffected", "version": "6.6.24", "versionType": "semver", "lessThanOrEqual": "6.6.*"}, {"status": "unaffected", "version": "6.7.12", "versionType": "semver", "lessThanOrEqual": "6.7.*"}, {"status": "unaffected", "version": "6.8.3", "versionType": "semver", "lessThanOrEqual": "6.8.*"}, {"status": "unaffected", "version": "6.9", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*"}], "programFiles": ["drivers/scsi/qla2xxx/qla_target.c"], "defaultStatus": "affected"}], "references": [{"url": "https://git.kernel.org/stable/c/b73377124f56d2fec154737c2f8d2e839c237d5a"}, {"url": "https://git.kernel.org/stable/c/d7a68eee87b05d4e29419e6f151aef99314970a9"}, {"url": "https://git.kernel.org/stable/c/67b2d35853c2da25a8ca1c4190a5e96d3083c2ac"}, {"url": "https://git.kernel.org/stable/c/a859f6a8f4234b8ef62862bf7a92f1af5f8cd47a"}, {"url": "https://git.kernel.org/stable/c/09c0ac18cac206ed1218b1fe6c1a0918e5ea9211"}, {"url": "https://git.kernel.org/stable/c/8de1584ec4fe0ebea33c273036e7e0a05e65c81d"}, {"url": "https://git.kernel.org/stable/c/8f0d32004e3a572bb77e6c11c2797c87f8c9703d"}, {"url": "https://git.kernel.org/stable/c/ec7587eef003cab15a13446d67c3adb88146a150"}, {"url": "https://git.kernel.org/stable/c/a27d4d0e7de305def8a5098a614053be208d1aa1"}], "x_generator": {"engine": "bippy-1.2.0"}, "descriptions": [{"lang": "en", "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Fix command flush on cable pull\n\nSystem crash due to command failed to flush back to SCSI layer.\n\n BUG: unable to handle kernel NULL pointer dereference at 0000000000000000\n PGD 0 P4D 0\n Oops: 0000 [#1] SMP NOPTI\n CPU: 27 PID: 793455 Comm: kworker/u130:6 Kdump: loaded Tainted: G OE --------- -
