Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the shstkpopsigframe function not checking the return value of mmapreadlockkillable and not marki...

CVE-2026-43016

The CVE-2026-43016 entries describe a use-after-free in the Linux kernel BPF sockmap path (sockmap) affecting AF_UNIX sockets. The issue occurs in sk_psock_verdict_data_ready(), when the peer’s sk_socket may be freed after an RCU grace period, while the sender holds the peer’s refcount. The root ...

CVE-2026-31669

The CVE-2026-31669 entry pertains to the Linux kernel MPTCP code. A use-after-free could occur in IPv6 subflow sockets due to premature copying of tcpv6_prot into tcpv6_prot_override during early init, before proto_register(&tcpv6_prot) and its SLAB_TYPESAFE_BY_RCU cache is established. Consequen...

SUSE CVE-2026-31526

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix exception exit lock checking for subprogs processbpfexitfull passes checklock = !curframe to checkresourceleak, which is false in cases when bpfthrow is called from a static subprog. This makes checkresourceleak to skip...

CVE-2026-31526

Summary: CVE-2026-31526 concerns the Linux kernel BPF verifier. A defect in exception exits for BPF subprograms allowed ORC unwinding to proceed without releasing user-held locks, risking resource leaks and instability. The root cause: process_bpf_exit_full() could set check_lock=false for except...

CVE-2026-31480

CVE-2026-31480 concerns a Linux kernel deadlock in CPU hotplug when tracing with osnoise. The vulnerability arises from a lock-ordering issue: a mutex_lock on interface_lock is taken while osnoise_sleep() and subsequent actions hold cpu hotplug state, followed by cpus_read_lock(), which can cause...
