CVE-2026-89499

A flaw was found in the Linux kernel's ring-buffer component. When a remote reader update fails during a page swap, the system incorrectly proceeds as if the swap succeeded. This can lead to log flooding, potentially causing a denial of service by exhausting system resources or hindering system...

The vulnerability of the page_swap_entry() function in the include/linux/swap.h module of the Linux kernel allows a hacker to trigger a service failure.

The vulnerability of the pageswapentry function in the include/linux/swap.h module of the Linux kernel is related to improper control of resource identifiers “resource injection”. Exploiting this vulnerability could allow an attacker to cause a service failure...

In the Linux kernel, the following vulnerability has been resolved: Ring-buffer: Fixed a race condition between readers and resize checks. The reader code in rbgetreaderpage swaps a new reader page into the ring buffer by using cmpxchg on old-list.prev-next to point it to the new page. After that...
