The vulnerability of the queueattrstore() function in the block/blk-sysfs.c module, which supports the block-level kernel in the Linux operating system, allows a attacker to cause a service failure.

The vulnerability of the queueattrstore function in the block/blk-sysfs.c module, which supports the block-level kernel in the Linux operating system, is related to the occurrence of mutual locking. Exploiting this vulnerability could allow a attacker to cause service failures...

15-Year-Old GhostLock Flaw Enables Root and Container Escape on Most Linux Distros

Researchers at Nebula Security have disclosed GhostLock CVE-2026-43499, a 15-year-old Linux kernel flaw that lets any logged-in user take full root control of a machine that has not been patched. The vulnerable code has shipped by default in essentially every mainstream distribution since 2011. T...

New "Bad Epoll" Linux Kernel Flaw Lets Unprivileged Users Gain Root, Hits Android

A newly disclosed Linux kernel flaw called Bad Epoll CVE-2026-46242 lets an ordinary user with no special access take full control of a machine as root. It affects Linux desktops, servers, and Android, and a fix is out. Bad Epoll sits in the same small stretch of kernel code where Anthropic's mos...

kernel: mptcp: fix slab-use-after-free in __inet_lookup_established

A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. Due to incorrect memory allocation for IPv6 subflow child sockets, a use-after-free vulnerability exists. A remote attacker could exploit this by triggering concurrent lookups in the kernel's hash table, potentially leadin...

kernel: exit: prevent preemption of oopsing TASK_DEAD task

A flaw was found in the Linux kernel. During the exit process of a task that has encountered an error, the system can incorrectly allow the task to be interrupted. This can lead to improper management of the task's memory, potentially causing memory corruption. Such an issue could allow a local...

kernel: net/sched: act_pedit: extend the writable skb range per key

A flaw was found in the Linux kernel's traffic control packet editing pedit subsystem. In tcfpeditact, the copy-on-write COW range for skbensurewritable is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can...
