"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: pm8001: Fix use-after-free in pm8001_queue_command()\n\nCommit e29c47fe8946 (\"scsi: pm8001: Simplify pm8001_task_exec()\") refactors\npm8001_queue_command(), however it introduces a potential cause of a double\nfree scenario when it changes the function to return -ENODEV in case of phy\ndown/device gone state.\n\nIn this path, pm8001_queue_command() updates task status and calls\ntask_done to indicate to upper layer that the task has been handled.\nHowever, this also frees the underlying SAS task. A -ENODEV is then\nreturned to the caller. When libsas sas_ata_qc_issue() receives this error\nvalue, it assumes the task wasn't handled/queued by LLDD and proceeds to\nclean up and free the task again, resulting in a double free.\n\nSince pm8001_queue_command() handles the SAS task in this case, it should\nreturn 0 to the caller indicating that the task has been handled."

"value": "AV:L - The pm8001 is a PCI-based SAS/SATA host bus adapter driver. Triggering this vulnerability requires local access to submit SCSI/ATA commands to a device managed by this HBA, which is done through local SCSI device interfaces.\nAC:L - The vulnerability triggers deterministically when I/O is submitted to a SATA device that is in the \"gone\" state. The attacker can control the device removal (e.g., by physically disconnecting a SATA drive or through hotplug) and then issue I/O, reliably triggering the double-free.\nPR:L - Submitting SCSI commands requires access to SCSI device files (e.g., /dev/sdX), which typically requires at least basic user-level access with appropriate device permissions. Root is not strictly required if the user has group access to the device.\nUI:N - No user interaction is required. The attacker can trigger the vulnerability by issuing I/O commands to a gone device independently.\nS:U - The vulnerability affects the kernel within its own security authority. There is no crossing of a security boundary such as a VM escape or sandbox escape.\nC:H - A double-free on slab memory (kmem_cache) is a powerful exploitation primitive. Through heap spraying, an attacker can control the contents of the reallocated object, potentially achieving arbitrary kernel memory read capabilities.\nI:H - The double-free allows an attacker to reclaim the freed slab object with controlled data, enabling type confusion and arbitrary kernel memory write primitives that can lead to code execution.\nA:H - The double-free will at minimum cause a kernel crash/panic when the slab allocator detects corruption, and can also be used to cause repeated crashes for denial of service."
