CVE-2025-71271 Details
Description
In the Linux kernel, the following vulnerability has been resolved: hfsplus: ensure sb->s_fs_info is always cleaned up When hfsplus was converted to the new mount api a bug was introduced by changing the allocation pattern of sb->s_fs_info. If setup_bdev_super() fails after a new superblock has been allocated by sget_fc(), but before hfsplus_fill_super() takes ownership of the filesystem-specific s_fs_info data it was leaked. Fix this by freeing sb->s_fs_info in hfsplus_kill_super().
A vulnerability in the Linux kernel's HFS+ filesystem implementation can lead to a memory leak of filesystem-specific information. This issue arises from a change in the allocation pattern of the superblock's filesystem info data when HFS+ was updated to use the new mount API. If the block device superblock setup fails after a new superblock is allocated but before the filesystem info is properly assigned, the data is left unfreed, causing a leak. The vulnerability affects the Linux kernel's stable releases.
Users can upgrade to the latest stable version of the Linux kernel, where this vulnerability has been addressed.
