Amazon Linux 2023 : bpftool6.12, kernel6.12, kernel6.12-devel (ALAS2023-2026-1423)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1423 advisory. In the Linux kernel, the following vulnerability has been resolved: net: use dstdevrcu in sksetupcaps CVE-2025-40170 In the Linux kernel, the following vulnerability has been resolved:...

The vulnerability of the `virtio_net_hdr_to_skb()` function in the `include/linux/virtio_net.h` header of the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the virtionethdrtoskb function in the include/linux/virtionet.h header of the Linux operating system is related to the pointer manipulation. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2026-23064

In the Linux kernel, the following vulnerability has been resolved: net/sched: actife: avoid possible NULL deref tcfifeencode must make sure ifeencode does not return NULL. syzbot reported: Oops: general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 1 SMP KASAN NOP...

UBUNTU-CVE-2026-23074

In the Linux kernel, the following vulnerability has been resolved: net/sched: Enforce that teql can only be used as root qdisc Design intent of teql is that it is only supposed to be used as root qdisc. We need to check for that constraint. Although not important, I will describe the scenario th...

CVE-2026-23105

In the Linux kernel, the following vulnerability has been resolved: net/sched: qfq: Use clisactive to determine whether class is active in qfqrmfromag This is more of a preventive patch to make the code more consistent and to prevent possible exploits that employ child qlen manipulations on qfq...

CVE-2026-23105

CVE-2026-23105 (Linux kernel) : A fix in the net/sched/qfq code changes the activation check of a class from relying on the child qdisc’s qlen to using cl_is_active in qfq_rm_from_ag. This patch makes activation determination more consistent and aims to prevent exploits that could manipulate chil...
