CVE-2022-50715
In the Linux kernel, the following vulnerability has been resolved: md/raid1: stop mdx_raid1 thread when raid1 array run failed fail run raid1 array when we assemble array with the inactive disk only, but the mdx_raid1 thread were not stop, Even if the associated resources have been released. it will caused a NULL dereference when we do poweroff. This causes the following Oops: [ 287.587787] BUG: kernel NULL pointer dereference, address: 0000000000000070 [ 287.594762] #PF: supervisor read access in kernel mode [ 287.599912] #PF: error_code(0x0000) - not-present page [ 287.605061] PGD 0 P4D 0 [ 287.607612] Oops: 0000 [#1] SMP NOPTI [ 287.611287] CPU: 3 PID: 5265 Comm: md0_raid1 Tainted: G U 5.10.146 #0 [ 287.619029] Hardware name: xxxxxxx/To be filled by O.E.M, BIOS 5.19 06/16/2022 [ 287.626775] RIP: 0010:md_check_recovery+0x57/0x500 [md_mod] [ 287.632357] Code: fe 01 00 00 48 83 bb 10 03 00 00 00 74 08 48 89 ......
