In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921s: fix potential hung tasks during chip recovery During chip recovery e.g. chip reset, there is a possible situation that kernel worker resetwork is holding the lock and waiting for kernel thread statworker to b...

CVE-2024-40977

CVE-2024-40977 is described in connected MiracleLinux advisory as a Linux kernel fix for the wifi: mt76: mt7921s: fix potential hung tasks during chip recovery. The root cause is a deadlock during chip recovery where kernel worker reset_work waits for stat_worker which itself waits for the same l...

CVE-2024-40972 ext4: do not create EA inode under buffer lock

In the Linux kernel, the following vulnerability has been resolved: ext4: do not create EA inode under buffer lock ext4xattrsetentry creates new EA inodes while holding buffer lock on the external xattr block. This is problematic as it nests all the allocation locking which acquires locks on othe...

CVE-2024-40969

CVE-2024-40969 (Linux kernel, f2fs) is confirmed to affect the f2fs shutdown path. The root cause is that shutdown does not verify the thaw error when the filesystem is read-only, which can lead to a deadlock during shutdown (via s b_start_write, set RO, and then thaw). The available connected do...
