CVE-2026-46145 RDMA/mana: Validate rx_hash_key_len

In the Linux kernel, the following vulnerability has been resolved: RDMA/mana: Validate rxhashkeylen Sashiko points out that rxhashkeylen comes from a uAPI structure and is blindly passed to memcpy, allowing the userspace to trash kernel memory. Bounds check it so the memcpy cannot overflow...

CVE-2026-46145

The CVE-2026-46145 vulnerability affects the Linux kernel, specifically the RDMA/mana component. A user-supplied rx_hash_key_len value supplied via a uAPI structure is blindly passed to memcpy, enabling localized kernel memory corruption if bounds checks are not enforced. Reports from multiple so...

CVE-2026-46120

Concrete details found: CVE-2026-46120 affects the Linux kernel ip6_gre machinery. The issue is in ip6erspan_changelink(), which wrongly uses dev_net(dev) instead of the correct per-netns hash resolved by link_net, after a patch series that fixed per-netns resolution in ip6erspan_newlink(). This ...

CVE-2026-46116

CVE-2026-46116 affects the Linux kernel xfrm subsystem (xfrm_state). The root cause is a local-use-after-free in __xfrm_state_delete due to unsafe deletions from byseq/byspi hash chains. The patch changes deletions to hlist_del_init_rcu and uses hlist_unhashed() checks, preventing writes after LI...
