Description OSIDB Bzimport 2025-12-04 17:01:59 UTC
In the Linux kernel, the following vulnerability has been resolved:

scsi: sg: Do not sleep in atomic context

sg_finish_rem_req() calls blk_rq_unmap_user(). The latter function may
sleep. Hence, call sg_finish_rem_req() with interrupts enabled instead
of disabled.
