Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-05-08 15:31

Details

In the Linux kernel, the following vulnerability has been resolved:

xfs: remove xfs_attr_leaf_hasname

The calling convention of xfs_attr_leaf_hasname() is problematic, because it returns a NULL buffer when xfs_attr3_leaf_read fails, a valid buffer when xfs_attr3_leaf_lookup_int returns -ENOATTR or -EEXIST, and a non-NULL buffer pointer for an already released buffer when xfs_attr3_leaf_lookup_int fails with other error values.

Fix this by simply open coding xfs_attr_leaf_hasname in the callers, so that the buffer release code is done by each caller of xfs_attr3_leaf_read.

Severity ?

7.8 (High)
