CVE-2022-49130
In CVE-2022-49130, the Linux kernel ath11k subsystem was fixed by replacing mhi_async_power_up() with mhi_sync_power_up() in the MHI path. The crash occurred when amss.bin was missing and ath11k_pci was removed, since the async variant did not check errors. The sync variant adds error checking an...
CVE-2022-49120
CVE-2022-49120 pertains to the Linux kernel SCSI pm8001 path. The vulnerability is a task leak in pm8001_send_abort_all() where allocated SAS tasks may not be freed if pm8001_tag_alloc() or pm8001_mpi_build_cmd() fail. The fix ensures proper freeing of the SAS task in those failure paths. Public ...
