Summary
In the Linux kernel, the following vulnerability has been resolved: raid10: cleanup memleak at raid10_make_request If raid10_read_request or raid10_write_request registers a new request and the REQ_NOWAIT flag is set, the code does not free the malloc from the mempool. unreferenced object 0xffff8884802c3200 (size 192): comm "fio", pid 9197, jiffies 4298078271 hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 88 41 02 00 00 00 00 00 .........A...... 08 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace (crc c1a049a2): __kmalloc+0x2bb/0x450 mempool_alloc+0x11b/0x320 raid10_make_request+0x19e/0x650 [raid10] md_handle_request+0x3b3/0x9e0 __submit_bio+0x394/0x560 __submit_bio_noacct+0x145/0x530 submit_bio_noacct_nocheck+0x682/0x830 __blkdev_direct_IO_async+0x4dc/0x6b0 blkdev_read_iter+0x1e5/0x3b0 __io_read+0x230/0x1110 io_read+0x13/0x30 io_issue_sqe+0x134/0x1180 io_submit_sqes+0x48c/0xe90 __do_sys_io_uring_enter+0x574/0x8b0 do_syscall_64+0x5c/0xe0 entry_SYSCALL_64_after_hwframe+0x76/0x7e V4: changing backing tree to see if CKI tests will pass.
