CVE-2025-21911
Description
In the Linux kernel, the following vulnerability has been resolved:drm/imagination: avoid deadlock on fence releaseDo scheduler queue fence release processing on a workqueue, ratherthan in the release function itself.Fixes deadlock issues such as the following:[ 607.400437] ============================================[ 607.405755] WARNING: possible recursive locking detected[ 607.415500] --------------------------------------------[ 607.420817] weston:zfq0/24149 is trying to acquire lock:[ 607.426131] ffff000017d041a0 (reservation_ww_class_mutex){+.+.}-{3:3}, at: pvr_gem_object_vunmap+0x40/0xc0 [powervr][ 607.436728] but task is already holding lock:[ 607.442554] ffff000017d105a0 (reservation_ww_class_mutex){+.+.}-{3:3}, at: dma_buf_ioctl+0x250/0x554[ 607.451727] other info that might help us debug this:[ 607.458245] Possible unsafe locking scenario:[ 607.464155] CPU0[ 607.466601] ----[ 607.469044] lock(reservation_ww_class_mutex);[ 607.473584] lock(reservation_ww_class_mutex);[ 607.478114] *** DEADLOCK ***
