rxkad Page-Cache Write via CVE-2026-43500

CVE-2026-43500 exploits a memory-corruption vulnerability in the Linux kernel's RxRPC authentication subsystem rxkad. When a crafted DATA packet is delivered to an AFRXRPC socket configured with an attacker-controlled rxkad session key, the kernel's rxkadverifypacket1 function performs an in-plac...

CVE-2026-43502

A flaw was found in the Linux kernel, specifically within the Remote Direct Memory Access RDMA subsystem's handling of zerocopy send operations. When a zerocopy send fails before the message is attached to the sending socket, the kernel may incorrectly clean up the associated memory. This can lea...

USN-8291-1: Linux kernel (Intel IoTG Real-time) vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - SMB network file system; - Netfilter; - iouring subsystem; CVE-2024-35862, CVE-2024-50060, CVE-2026-23274,...

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: "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...

CVE-2026-9117

Summary: CVE-2026-9117 is a type confusion issue in the GFX stack of Google Chrome on Linux and ChromeOS before 148.0.7778.179. The vulnerability could allow a remote attacker who has already compromised the renderer process to potentially escape the Chrome sandbox via a crafted video file. Affec...

kernel: "Dirty Frag" ESP XFRM variant is a new universal Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The...

Astra Linux – Vulnerability in Linux 5.10, Linux

A out-of-bounds read flaw was discovered in the Linux kernel’s TeleTYpe subsystem. The issue arises when a user triggers a race condition using ioctls TIOCSPTLCK, TIOCGPTPEER, TIOCSTI, and TCXONC, accompanied by memory leakage in the flushtoldisc function. This flaw allows a local user to crash t...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ALSA: usx2y – Do not call freepagesexact with a NULL address. Unlike some other functions, we cannot pass a NULL pointer to freepagesexact. Add a proper NULL check to avoid potential errors...

Astra Linux – Vulnerability in Parsec

The vulnerability of the pdpl-user utility in the PARSEC security subsystem is related to improper memory release after its use. Exploiting this vulnerability allows an attacker to cause a service failure...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: ASoC: soc-pcm: Added a NULL check in BE reparenting. A NULL check was also added to the dpcmbereparent API, to handle kernel NULL pointer dereferencing errors. This issue occurred during fuzzing tests...
