"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: fix transaction abort on set received ioctl due to item overflow\n\nIf the set received ioctl fails due to an item overflow when attempting to\nadd the BTRFS_UUID_KEY_RECEIVED_SUBVOL we have to abort the transaction\nsince we did some metadata updates before.\n\nThis means that if a user calls this ioctl with the same received UUID\nfield for a lot of subvolumes, we will hit the overflow, trigger the\ntransaction abort and turn the filesystem into RO mode. A malicious user\ncould exploit this, and this ioctl does not even requires that a user\nhas admin privileges (CAP_SYS_ADMIN), only that he/she owns the subvolume.\n\nFix this by doing an early check for item overflow before starting a\ntransaction. This is also race safe because we are holding the subvol_sem\nsemaphore in exclusive (write) mode.\n\nA test case for fstests will follow soon."
