In the Linux kernel, the following vulnerability has been resolved: tty: ngsm: requires CAPNETADMIN to attach NGSM0710 ldisc. Any unprivileged user can attach to NGSM0710 ldisc, but it still requires CAPNETADMIN to create a GSM network. Additionally, it requires the initial namespace setting of...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net/sched: netem: account for backlog updates from child qdisc Generally, the qlen of any classful qdisc should reflect the number of packets held by the qdisc itself and all its children. In the case of netem, qlen only accounts...

CVE-2026-74267

In the Linux kernel, the following vulnerability has been resolved: net/sched: schcodel: Do not call qdisctreereducebacklog during peek before restoring qlen Whenever codel drops packets during peek, it calls qdisctreereducebacklog. An issue arises because it calls qdisctreereducebacklog before i...

CVE-2026-68337

The CVE affects the Linux kernel BPF redirect helpers (bpf_redirect* and skb_do_redirect) and the bpf_net_context flow. The issue arose when a BPF program ran via tc BPF paths and accessed current->bpf_net_context unconditionally, leading to NULL dereferences. Specifically, redirects via tc qd...

EUVD-2026-55519

In the Linux kernel, the following vulnerability has been resolved: net/sched: serialize qdiscrtablist against concurrent get/put qdiscgetrtab and qdiscputrtab mutate the process-global singly linked list qdiscrtablist and a plain non-atomic 'int refcnt' with no lock. This was only safe because...

CVE-2026-68138

The CVE-2026-68138 issue concerns a race in the Linux kernel networking scheduler (net/sched) where qdisc_rtab_list and a non-atomic refcnt are mutated without proper locking. The historical RTNL mutex was supposed to serialize rate-table lookups, inserts, and frees, but CLS_FLOWER/TCF_PROTO_OPS_...
