In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix listxattr handling of corrupted xattr entries
Validate the xattr entry before reading its fields in f2fs_listxattr().
Return -EFSCORRUPTED when the entry is outside the valid xattr storage
area instead of returning a successful partial result.
A flaw was found in the f2fs file system within the Linux kernel. This vulnerability arises from inadequate validation of extended attribute (xattr) entries during the f2fs_listxattr() function's operation. A local attacker could potentially create a corrupted xattr entry, causing the system to attempt to read data from outside the valid xattr storage area. This could lead to unexpected system behavior or the disclosure of sensitive information.
