CVE-2026-80863

CVE-2026-80863 is a slab out-of-bounds write (size 4) in the Linux kernel's RDMA/rxe (Soft-RoCE) driver, specifically in free_rd_atomic_resources() at drivers/infiniband/sw/rxe/rxe_qp.c. The root cause is that max_dest_rd_atomic is updated before the old array is freed, causing the free path to i...

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...

CVE-2026-80850

CVE-2026-80850 is a use-after-free in the Linux kernel's TCP-AO implementation. During tcp_v4_connect(), a race exists between initial key validation and the later L3-master resolution in tcp_ao_connect_init(). If the bound network device is detached from its VRF in that window, the only AO key i...
