CVE-2022-50668

Summary: CVE-2022-50668 is a Linux kernel ext4 mbcache deadlock issue caused by a non-atomic update of the e_reusable bit in a shared bitfield, which can lead to infinite retries in ext4_xattr_block_set() when manipulating xattr blocks. The fix uses atomic bit operations to prevent the race with ...

kernel: ext4: fix deadlock due to mbcache entry corruption

A deadlock vulnerability was found in the ext4 filesystem in the Linux kernel. When manipulating extended attribute xattr blocks, a race condition in non-atomic bitfield updates can cause the mbcache entry state to become corrupted. This leads to an infinite loop in ext4xattrblockset where the co...

CVE-2021-46933 usb: gadget: f_fs: Clear ffs_eventfd in ffs_data_clear.

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: ffs: Clear ffseventfd in ffsdataclear. ffsdataclear is indirectly called from both ffsfskillsb and ffsep0release, so it ends up being called twice when userland closes ep0 and then unmounts ffs. If userland provided ...
