CVE-2026-43494

CVE-2026-43494 affects the Linux kernel’s net/rds zerocopy path. When iov_iter_get_pages2() fails in rds_message_zcopy_from_user(), pinned pages are released and rm->data.op_mmp_znotifier is cleared, but rm->data.op_nents may not be reset. This leads to the cleanup loop in rds_message_purge...

kernel: Read root-owned files as an unprivileged user

A vulnerability was found in the Linux kernel that allows an unprivileged local user to read sensitive files normally restricted to the root user. The flaw occurs during process exit, where a brief window allows an attacker to intercept file access from a privileged process before it fully...

kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged...

9-Year-Old Linux Kernel Flaw Enables Root Command Execution on Major Distros

Cybersecurity researchers have disclosed details of a vulnerability in the Linux kernel that remained undetected for nine years. The vulnerability, tracked as CVE-2026-46333 CVSS score: 5.5, is a case of improper privilege management that could permit an unprivileged local user to disclose...

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 lack of a check to re-export GEM objects in accel/ivpu. This could lead to the loss of buffer...
