CVE ID :CVE-2026-64185<\/p>\n
Published : July 19, 2026, 4:18 p.m. | 1\u00a0hour, 23\u00a0minutes ago<\/p>\n
Description :In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
sysfs: don’t remove existing directory on update failure<\/p>\n
When sysfs_update_group() is called for a named group and create_files()
\nfails (e.g. -ENOMEM), internal_create_group() calls kernfs_remove(kn) on
\nthe group directory. In the update path, kn was obtained via
\nkernfs_find_and_get() and refers to a directory that already existed
\nbefore this call. Removing it silently destroys a sysfs group that the
\ncaller did not create.<\/p>\n
Only remove the directory if we created it ourselves. On update failure
\nthe directory remains as it is left empty by remove_files() inside
\ncreate_files(), but can be repopulated by a retry.<\/p>\n
Severity: 0.0 | NA<\/p>\n
