CVE-2026-99160
A flaw was found in the Linux kernel's ring buffer subsystem. A local user can exploit this vulnerability to cause a Denial of Service DoS by crashing the kernel. The issue occurs when reading ring buffer metadata files for a central processing unit CPU that has never come online, resulting in a...
CVE-2026-99159
A flaw was found in the Linux kernel's ring-buffer subsystem. A local user can cause a Denial of Service DoS by crashing the system when interacting with persistent ring buffers. Due to an incorrect sub-buffer index calculation, the kernel leaves an entry uninitialized, resulting in a null pointe...
CVE-2026-99158
A flaw was found in the Linux kernel's ring buffer component. When a reader process accessing memory-mapped trace data catches up with a concurrent writer still committing events, the kernel incorrectly treats the temporary absence of data as an error and triggers a kernel warning. A local user...
