CVE ID : CVE-2025-40001<\/p>\n
Published : Oct. 18, 2025, 8:15 a.m. | 25\u00a0minutes ago<\/p>\n
Description : In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
scsi: mvsas: Fix use-after-free bugs in mvs_work_queue<\/p>\n
During the detaching of Marvell’s SAS\/SATA controller, the original code
\ncalls cancel_delayed_work() in mvs_free() to cancel the delayed work
\nitem mwq->work_q. However, if mwq->work_q is already running, the
\ncancel_delayed_work() may fail to cancel it. This can lead to
\nuse-after-free scenarios where mvs_free() frees the mvs_info while
\nmvs_work_queue() is still executing and attempts to access the
\nalready-freed mvs_info.<\/p>\n
A typical race condition is illustrated below:<\/p>\n
CPU 0 (remove) | CPU 1 (delayed work callback)
\nmvs_pci_remove() |
\n mvs_free() | mvs_work_queue()
\n cancel_delayed_work() |
\n kfree(mvi) |
\n | mvi-> \/\/ UAF<\/p>\n
Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensure
\nthat the delayed work item is properly canceled and any executing
\ndelayed work item completes before the mvs_info is deallocated.<\/p>\n
This bug was found by static analysis.<\/p>\n
Severity: 0.0 | NA<\/p>\n
