kernel: use-after-free in __blk_add_trace in kernel/trace/blktrace.c

A use-after-free vulnerability was found in the Linux kernel’s implementation of blktrace in the blkaddtrace function. A local attacker with permissions to run block trace instructions against a device can create a situation where the core blocktrace object is used after it is freed. The attacker...
