Threats tagged 'ghsa-7v4m-qg52-mxg3'

A vulnerability in the Linux kernel's btrfs filesystem code was identified in the function btrfs_encode_fh(). The function improperly handles three cases for file handle sizes, leading to a potential out-of-bounds write of 8 bytes when the parent exists and root IDs differ. This memory corruption issue was resolved by correcting the size returned and validating buffer length before writing. The vulnerability is rated high severity due to its potential impact on confidentiality, integrity, and availability.
