In the Linux kernel, the following vulnerability has been resolved: bpf: Use RCU-safe iteration in devmapredirectmulti SKB path The DEVMAPHASH branch in devmapredirectmulti uses hlistforeachentrysafe to iterate hash buckets, but this function runs under RCU protection called from...

CVE-2026-53094

The CVE affects the Linux kernel BPF/JIT path for dev-bound-only XDP programs. When constant blinding is enabled (bpf_jit_harden >= 2), bpf_jit_blind_constants() clones the program and bpf_jit_prog_release_other() frees the original, but offload->prog isn’t updated, leaving a stale pointer....

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix linked reg delta tracking when srcreg == dstreg Consider the case of rX += rX where srcreg and dstreg are pointers to the same bpfregstate in adjustregminmaxvals. The latter first modifies the dstreg in-place, and later ...

CVE-2026-53091

The CVE-2026-53091 issue concerns the Linux kernel’s handling of GSO packet headers during qdisc_pkt_len_segs_init(). The root cause is that many ndo_start_xmit() paths assume headers are already in skb->head, while tso_build_hdr() may copy from skb->data, and qdisc_pkt_len_segs_init() diss...

CVE-2026-53091 net: pull headers in qdisc_pkt_len_segs_init()

In the Linux kernel, the following vulnerability has been resolved: net: pull headers in qdiscpktlensegsinit Most ndostartxmit methods expects headers of gso packets to be already in skb-head. net/core/tso.c users are particularly at risk, because tsobuildhdr does a memcpyhdr, skb-data, hdrlen;...

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix same-register dst/src OOB read and pointer leak in sockops When a BPF sockops program accesses ctx fields with dstreg == srcreg, the SOCKOPSGETSK and SOCKOPSGETFIELD macros fail to zero the destination register in the...

CVE-2026-53070

In the Linux kernel, the following vulnerability has been resolved: sctp: disable BH before calling udptunnelxmitskb udptunnelxmitskb / udptunnel6xmitskb are expected to run with BH disabled. After commit 6f1a9140ecda "add xmit recursion limit to tunnel xmit functions", on the path:...

CVE-2026-53070

The CVE-2026-53070 issue affects the Linux kernel SCTP over UDP path. It concerns the IPv4/IPv6 sctp_udp_xmit code where xmit_skb() execution must occur with BH disabled; after a recursion-limit change, the context could migrate between CPUs, upsetting the dev_xmit_recursion pairing and potential...

CVE-2026-53055

CVE-2026-53055 concerns the Linux kernel crypto: hisilicon/sec2 module. Under heavy load, during packet transmission, the hardware may free the request memory (req) before the software finishes processing, causing a use-after-free when the software accesses the freed memory. The issue affects the...
