CVE-2026-64000

The CVE-2026-64000 entry refers to a Linux kernel vulnerability in the net: hsr subsystem where supervision frame handling could trigger an out-of-bounds access (OOB) due to an inadequate check when accessing TLV headers. The root cause is traced to insufficient linearization of the entire TLV he...

CVE-2026-63988

CVE-2026-63988 concerns a Linux kernel fix for sleeping in atomic context during sysfs path handling in bridge brport_store(). The root cause: brport_store() previously held the bridge lock for many attributes; now most attributes don’t require the lock. As a result, calling dev_set_promiscuity()...
