NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6_4_0-150600_10_5-rt package and not the kernel-livepatch-6_4_0-150600_10_5-rt package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

blk-mq: make sure active queue usage is held for bio_integrity_prep()

blk_integrity_unregister() can come if queue usage counter isn't held for one bio with integrity prepared, so this request may be completed with calling profile->complete_fn, then kernel panic.

Another constraint is that bio_integrity_prep() needs to be called before bio merge.

Fix the issue by:

  • call bio_integrity_prep() with one queue usage counter grabbed reliably

  • call bio_integrity_prep() before bio merge
