CVE-2021-47434 – xhci: Fix command ring pointer corruption while aborting a command
https://notcve.org/view.php?id=CVE-2021-47434
22 May 2024 — In the Linux kernel, the following vulnerability has been resolved: xhci: Fix command ring pointer corruption while aborting a command The command ring pointer is located at [6:63] bits of the command ring control register (CRCR). All the control bits like command stop, abort are located at [0:3] bits. While aborting a command, we read the CRCR and set the abort bit and write to the CRCR. The read will always give command ring pointer as all zeros. So we essentially write only the control bits. • https://git.kernel.org/stable/c/22bcb65ea41072ab5d03c0c6290e04e0df6d09a0 •
CVE-2021-47433 – btrfs: fix abort logic in btrfs_replace_file_extents
https://notcve.org/view.php?id=CVE-2021-47433
22 May 2024 — In the Linux kernel, the following vulnerability has been resolved: btrfs: fix abort logic in btrfs_replace_file_extents Error injection testing uncovered a case where we'd end up with a corrupt file system with a missing extent in the middle of a file. This occurs because the if statement to decide if we should abort is wrong. The only way we would abort in this case is if we got a ret != -EOPNOTSUPP and we called from the file clone code. However the prealloc code uses this path too. • https://git.kernel.org/stable/c/0e32a2b85c7d92ece86c17dfef390c5ed79c6378 •
