UBUNTU-CVE-2024-56631: Use After Free

Q: What level of access does an attacker need?

Exploitation requires local access, high privileges, high attack complexity, and additional attack requirements. No user interaction is required.

Q: What is the potential impact if exploitation succeeds?

The vulnerability is rated high severity with high impacts to confidentiality, integrity, and availability. The affected flaw is a slab use-after-free in the SCSI generic driver's release path.

Q: Which Ubuntu kernel packages are listed as affected?

The listed software includes ubuntu/linux, ubuntu/linux-aws, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-fips, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, and ubuntu/linux-gcp-fips.

Updated

In the Linux kernel, the following vulnerability has been resolved: scsi: sg: Fix slab-use-after-free read in sgrelease() Fix a use-after-free bug in sgrelease(), detected by syzbot with KASAN: BUG: KASAN: slab-use-after-free in lockrelease+0x151/0xa30 kernel/locking/lockdep.c:5838 mutexunlockslowpath+0xe2/0x750 kernel/locking/mutex.c:912 sgrelease+0x1f4/0x2e0 drivers/scsi/sg.c:407 In sgrelease(), the function krefput(&sfp->fref, sgremovesfp) is called before releasing the openrellock mutex. The krefput() call may decrement the reference count of sfp to zero, triggering its cleanup through sgremovesfp(). This cleanup includes scheduling deferred work via sgremovesfpusercontext(), which ultimately frees sfp. After krefput(), sgrelease() continues to unlock openrellock and may reference sfp or sdp. If sfp has already been freed, this results in a slab-use-after-free error. Move the krefput(&sfp->fref, sgremovesfp) call after unlocking the openrellock mutex. This ensures: - No references to sfp or sdp occur after the reference count is decremented. - Cleanup functions such as sgremovesfp() and sgremovesfpusercontext() can safely execute without impacting the mutex handling in sgrelease(). The fix has been tested and validated by syzbot. This patch closes the bug reported at the following syzkaller link and ensures proper sequencing of resource cleanup and mutex operations, eliminating the risk of use-after-free errors in sgrelease().
