In the Linux kernel, the following vulnerability has been resolved: btrfs: handle errors from btrfs_dec_ref() properly In walk_up_proc() we BUG_ON(ret) from btrfs_dec_ref(). This is incorrect, we have proper error handling here, return the error. • https://git.kernel.org/stable/c/a7f16a7a709845855cb5a0e080a52bda5873f9de https://git.kernel.org/stable/c/5eb178f373b4f16f3b42d55ff88fc94dd95b93b1 •

https://notcve.org/view.php?id=CVE-2024-46752
In the Linux kernel, the following vulnerability has been resolved: btrfs: replace BUG_ON() with error handling at update_ref_for_cow() Instead of a BUG_ON() just return an error, log an error message and abort the transaction in case we find an extent buffer belonging to the relocation tree that doesn't have the full backref flag set. This is unexpected and should never happen (save for bugs or a potential bad memory). • https://git.kernel.org/stable/c/b50857b96429a09fd3beed9f7f21b7bb7c433688 https://git.kernel.org/stable/c/0fbac73a97286a7ec72229cb9b42d760a2c717ac https://git.kernel.org/stable/c/41a0f85e268d72fe04f731b8ceea4748c2d65491 https://git.kernel.org/stable/c/f895db00c65e5d77c437cce946da9ec29dcdf563 https://git.kernel.org/stable/c/b56329a782314fde5b61058e2a25097af7ccb675 •
