CVE-2026-53111
CVE-2026-53111 is a Linux kernel issue where bpf_lwt_xmit_push_encap dereferences skb_dst(skb)->dev during test_run when skb->_skb_refdst is uninitialized, leading to a kernel crash. A patch and remediation include initializing skb->_skb_refdst before bpf_test_run_skb, as evidenced by Ro...
CVE-2026-53096 bpf: Use RCU-safe iteration in dev_map_redirect_multi() SKB path
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-2026-53096
CVE-2026-53096 affects Linux kernel code path in BPF dev_map_redirect_multi() where DEVMAP_HASH uses hlist_for_each_entry_safe() under RCU protection. The function iterates hash buckets without rcu_dereference(), exposing risk of partially constructed nodes on weakly-ordered architectures (ARM64,...
CVE-2026-53079
CVE-2026-53079 affects the Linux kernel networking path in net_sched. The issue is a memory leak where, during deferred qdisc drops, packets not freed on root qdisc due to missing TCQ_F_DEQUEUE_DROPS handling remain stranded on child to_free lists. The fix makes qdisc_dequeue_drop() fetch and che...
CVE-2026-53009 ice: fix double-free of tx_buf skb
In the Linux kernel, the following vulnerability has been resolved: ice: fix double-free of txbuf skb If icetso or icetxcsum fail, the error path in icexmitframering frees the skb, but the 'first' txbuf still points to it and is marked as valid ICETXBUFSKB. 'nexttouse' remains unchanged, so the...
CVE-2026-52997
The CVE-2026-52997 issue affects the Linux kernel’s net/sched sch_dualpi2 qdisc. The root cause was that dualpi2_change() could attempt to dequeue from the C-queue even when it was empty while packets resided in the L-queue, leading to a NULL skb dereference during limit/memlimit enforcement. The...
CVE-2026-52985
CVE-2026-52985 concerns the Linux kernel in the netdevsim feature, where the IP header in a dummy skb was not zero-initialized in nsim_dev_trap_skb_build. The issue arises from using skb_put instead of skb_put_zero, leading to uninitialized values in the IP header and potential memory/safety impl...
CVE-2026-52982
The CVE-2026-52982 issue affects the Linux kernel driver rtl8150 for Realtek RTL8150 USB Ethernet devices. A use-after-free (UAF) can occur in rtl8150_start_xmit() when reading skb->len for tx_bytes statistics after usb_submit_urb() is issued, because the skb may be freed in the USB completion...
CVE-2026-52981 neigh: let neigh_xmit take skb ownership
In the Linux kernel, the following vulnerability has been resolved: neigh: let neighxmit take skb ownership neighxmit always releases the skb, except when no neighbour table is found. But even the first added user of neighxmit mpls relied on neighxmit to release the skb or queue it for tx. sashik...
