CVE-2026-64054
CVE-2026-64054 is a Linux kernel vulnerability in the net_shaper (Network Shaper API) subsystem. The function net_shaper_nl_group_doit() fails to deduplicate NET_SHAPER_A_LEAVES entries, so when userspace supplies the same leaf handle twice, the same parent pointer is stored twice in old_nodes[],...
CVE-2026-64058
The CVE-2026-64058 issue affects the Linux kernel netfs component, specifically netfs_read_folio(), which did not wait for ongoing writeback to finish. The root cause was that folio->private could be cleaned up by the collector before the writeback flag was cleared, leading to unreliable trust...
CVE-2026-64089
CVE-2026-64089 affects the Linux kernel Batman-Adv (batman-adv) TT code. The root cause is that last_changeset_len was declared as s16, which can wrap when values exceed 32767, producing a negative value that then propagates into a widened s32. This leads batadv_tt_prepare_tvlv_local_data() to al...
CVE-2026-64101
The CVE-2026-64101 issue affects the Linux kernel fwctl component, where the RPC input buffer for pds is validated too late.
