CVE-2022-50430

CVE-2022-50430 affects the Linux kernel mmc vub300 driver. The fix prevents calling blocking operations when the current task is not TASK_RUNNING by ensuring vub300_enable_sdio_irq() uses proper mutex usage and marks the current task as TASK_RUNNING in a sleepable context. This reduces a potentia...

CVE-2022-50436

CVE-2022-50436 : Linux kernel ext4 had a deadlock risk when ext4_unlink() extended the jbd2 transaction scope, because ext4_find_entry() could require setting up the directory encryption key inside a transaction.
