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-2026-53111 bpf: test_run: Fix the null pointer dereference issue in bpf_lwt_xmit_push_encap

In the Linux kernel, the following vulnerability has been resolved: bpf: testrun: Fix the null pointer dereference issue in bpflwtxmitpushencap The bpflwtxmitpushencap helper needs to access skbdstskb-dev to calculate the needed headroom: err = skbcowheadskb, len + LLRESERVEDSPACEskbdstskb-dev; B...

CVE-2026-53092

CVE-2026-53092 affects the Linux kernel’s BPF subsystem . The root cause is in register delta tracking when the same source and destination registers are used (e.g., rX += rX). In adjust_reg_min_max_vals(), the code mutates the destination in-place, and later, when evaluating the source register,...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ipvs: Do not keep the destdst entry if the device is going down. There is a race between the netdevnotifier function ipvsdstevent and the code that caches the dst entry for devices that are going down. Since the FIB can be notifi...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ipvs: fixed the NULL pointer dereference in the route error path of ipv4 null-ptr-deref. The IPv4 code path in ipvsgetoutrt calls dstlinkfailure, without ensuring that skb-dev is set. This leads to a NULL pointer dereference in...
