Message-ID: <2025091644-CVE-2023-53322-45ba@gregkh> Date: Tue, 16 Sep 2025 18:12:07 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-cve-announce@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...nel.org> Subject: CVE-2023-53322: scsi: qla2xxx: Wait for io return on terminate rport From: Greg Kroah-Hartman <gregkh@...nel.org> Description =========== In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Wait for io return on terminate rport System crash due to use after free. Current code allows terminate_rport_io to exit before making sure all IOs has returned. For FCP-2 device, IO's can hang on in HW because driver has not tear down the session in FW at first sign of cable pull. When dev_loss_tmo timer pops, terminate_rport_io is called and upper layer is about to free various resources. Terminate_rport_io trigger qla to do the final cleanup, but the cleanup might not be fast enough where it leave qla still holding on to the same resource. Wait for IO's to return to upper layer before resources are freed. The Linux kernel CVE team has assigned CVE-2023-53322 to this issue. Affected and fixed versions =========================== Fixed in 4.14.322 with commit 8a55556cd7e0220486163b1285ce11a8be2ce5fa Fixed in 4.19.291 with commit 4647d2e88918a078359d1532d90c417a38542c9e Fixed in 5.4.251 with commit d25fded78d88e1515439b3ba581684d683e0b6ab Fixed in 5.10.188 with commit a9fe97fb7b4ee21bffb76f2acb05769bad27ae70 Fixed in 5.15.121 with commit 079c8264ed9fea8cbcac01ad29040f901cbc3692 Fixed in 6.1.40 with commit 90770dad1eb30967ebd8d37d82830bcf270b3293 Fixed in 6.4.5 with commit 5bcdaafd92be6035ddc77fa76650cf9dd5b864c4 Fixed in 6.5 with commit fc0cba0c7be8261a1625098bd1d695077ec621c9 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2023-53322 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/scsi/qla2xxx/qla_attr.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/8a55556cd7e0220486163b1285ce11a8be2ce5fa https://git.kernel.org/stable/c/4647d2e88918a078359d1532d90c417a38542c9e https://git.kernel.org/stable/c/d25fded78d88e1515439b3ba581684d683e0b6ab https://git.kernel.org/stable/c/a9fe97fb7b4ee21bffb76f2acb05769bad27ae70 https://git.kernel.org/stable/c/079c8264ed9fea8cbcac01ad29040f901cbc3692 https://git.kernel.org/stable/c/90770dad1eb30967ebd8d37d82830bcf270b3293 https://git.kernel.org/stable/c/5bcdaafd92be6035ddc77fa76650cf9dd5b864c4 https://git.kernel.org/stable/c/fc0cba0c7be8261a1625098bd1d695077ec621c9
