A use after free flaw in the Linux Kernel SGI GRU driver in drivers/misc/sgi-gru/grufile.c found. A local user can call gru_file_unlocked_ioctl with GRU_SET_CONTEXT_OPTION and then triggering error path in gru_check_context_placement function. This leads to use after free in gru_unload_context function. Reference: <a href="https://www.spinics.net/lists/kernel/msg4518970.html">https://www.spinics.net/lists/kernel/msg4518970.html</a> Besides, this is a long existing bug which was introduced in 13 years ago: <a href="https://github.com/torvalds/linux/commit/55484c45dbeca2eec7642932ec3f60f8a2d4bdbf">https://github.com/torvalds/linux/commit/55484c45dbeca2eec7642932ec3f60f8a2d4bdbf</a>
