SUSE CVE-2026-80852

In the Linux kernel, the following vulnerability has been resolved: tls: device: fix out-of-bounds write in tlsappendfrag Found with syzkaller and a local syzbot instance running on top of a netdevsim TLS offload emulation; tlsdevice.c is otherwise only reachable on a machine with a NIC that...

CVE-2026-80852

CVE-2026-80852 is an out-of-bounds write in the Linux kernel's TLS device offload path (net/tls/tls_device.c). The root cause is that tls_push_data() skips its fragment-count check on an early MSG_MORE break, allowing num_frags to exceed MAX_SKB_FRAGS (17) when splice(SPLICE_F_MORE) calls are iss...

In the Linux kernel, the following vulnerability has been resolved: kcm: Serialise kcmsendmsg for the same socket. syzkaller reported UAF in kcmrelease. 0 The scenario is 1. Thread A builds a skb with MSGMORE and sets kcm-seqskb. 2. Thread A resumes building skb from kcm-seqskb but is blocked by...

CVE-2024-44946

CVE-2024-44946 (Linux kernel, KCM) has a confirmed UAF/double-free risk in kcm_release arising when one thread frees an skb still in the KCM write queue due to concurrent kcm_sendmsg() operations. The issue occurs when a thread building a MSG_MORE skb holds kcm->seq_skb while another thread co...
