UBUNTU-CVE-2024-53138

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: kTLS, Fix incorrect page refcounting The kTLS tx handling code is using a mix of getpage and pagerefinc APIs to increment the page reference. But on the release path mlx5ektlstxhandleresyncdumpcomp, only putpage is use...

UBUNTU-CVE-2023-52731

In the Linux kernel, the following vulnerability has been resolved: fbdev: Fix invalid page access after closing deferred I/O devices When a fbdev with deferred I/O is once opened and closed, the dirty pages still remain queued in the pageref list, and eventually later those may be processed in t...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from page reference counting of unaligned buffers in the bioreleasepages function...

kernel: tls: use-after-free with partial reads and async decrypt

A use-after-free vulnerability was found in the tls subsystem of the Linux kernel. The tlsdecryptsg function doesn't take references on the pages from clearskb, so the putpage in tlsdecryptdone releases them and a use-after-free can be triggered in processrxlist when trying to read from the...

CVE-2021-46911

In the Linux kernel, the following vulnerability has been resolved: chktls: Fix kernel panic Taking page refcount is not ideal and causes kernel panic sometimes. It's better to take txctx lock for the complete skb transmit, to avoid page cleanup if ACK received in middle...

Linux kernel security vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. The Linux kernel suffers from a security vulnerability that stems from the fact that the count of page references in use is not optimal, sometimes leading to kernel panics...

K14255532: Linux kernel vulnerability CVE-2019-11487

Security Advisory Description The Linux kernel before 5.1-rc5 allows page-refcount reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipefsi.h,...

DEBIAN-CVE-2022-26364

x86 pv: Insufficient care with non-coherent mappings This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE. Xen maintains a type reference count for pages, in addition to a regular reference count. This scheme is used to...

kernel: Count overflow in FUSE request leading to use-after-free issues.

A flaw was found in the Linux kernel's implementation of the FUSE filesystem, where it allows a page reference counter overflow. If a page reference counter overflows into a negative value, it can be placed back into the "free" list for reuse by other applications. This flaw allows a local attack...
