UBUNTU-CVE-2022-50552
In the Linux kernel, the following vulnerability has been resolved: blk-mq: use quiesced elevator switch when reinitializing queues The hctx's runwork may be racing with the elevator switch when reinitializing hardware queues. The queue is merely frozen in this context, but that only prevents...
CVE-2022-50554 blk-mq: avoid double ->queue_rq() because of early timeout
In the Linux kernel, the following vulnerability has been resolved: blk-mq: avoid double -queuerq because of early timeout David Jeffery found one double -queuerq issue, so far it can be triggered in VM use case because of long vmexit latency or preempt latency of vCPU pthread or long page fault ...
CVE-2022-50554
CVE-2022-50554 affects the Linux kernel's blk-mq subsystem. The vulnerability arises from a race around IO request queuing, where an in-flight ->queue_rq() may be double-called due to an timeout occurring after blk_mq_start_request() but before completion, potentially causing a kernel panic. T...

CVE-2022-50552
CVE-2022-50552 : In the Linux kernel, the blk-mq path had a race where hctx->run_work could race with the elevator switch during reinitialization of hardware queues, potentially leading to use-after-free and kernel panics. The fix switches to a quiesced elevator switch and makes the previous e...

CVE-2022-50550
CVE-2022-50550 affects the Linux kernel’s blk-iolatency component. The flaw arises when a gendisk is initialized but add_disk() fails; iolatency is initialized during init but not cleaned up in error handling, causing a memory leak. The root cause is that cleanup previously relied on del_gendisk(...

CVE-2022-50516
The CVE-2022-50516 issue in the Linux kernel’s fs: dlm was fixed by a patch that ensures sb_lvbptr is not dereferenced when DLM_LKF_VALBLK is involved, avoiding a potential NULL/dangling pointer dereference in memcpy paths. The fix copies lvbptr arrays only when DLM_LKF_VALBLK is set (not merely ...
