CVE-2023-54185 Details
Description
In the Linux kernel, the following vulnerability has been resolved: btrfs: remove BUG_ON()'s in add_new_free_space() At add_new_free_space() we have these BUG_ON()'s that are there to deal with any failure to add free space to the in memory free space cache. Such failures are mostly -ENOMEM that should be very rare. However there's no need to have these BUG_ON()'s, we can just return any error to the caller and all callers and their upper call chain are already dealing with errors. So just make add_new_free_space() return any errors, while removing the BUG_ON()'s, and returning the total amount of added free space to an optional u64 pointer argument.
A vulnerability in the Linux kernel's Btrfs file system has been addressed. The issue involved the use of 'BUG_ON()' statements in the 'add_new_free_space()' function, which were intended to handle rare errors related to memory allocation failures. These 'BUG_ON()' statements were unnecessary, as the function could simply return errors to the caller, which is already equipped to handle such situations. The vulnerability has been resolved by modifying 'add_new_free_space()' to return errors instead of using 'BUG_ON()', while also providing the total amount of added free space to an optional pointer argument.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
