Astra Linux – Vulnerability in Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: block: fixed a memory leak in blkdevissuezeropages. The check for the fatal signal was moved before the bioalloc function, thereby preventing a memory leak when BLKDEVZEROKILLABLE is set and a fatal signal is pending. Previously,...
CVE-2026-46115
A flaw was found in the Linux kernel's block subsystem. The biovecphysmergeable function, which combines physically contiguous memory segments, lacked a check to ensure these segments belonged to the same device page map devpagemap. This omission could result in the incorrect identification of th...
UBUNTU-CVE-2026-46115
In the Linux kernel, the following vulnerability has been resolved: block: add pgmap check to biovecphysmergeable biovecphysmergeable is used by the request merge, DMA mapping, and integrity merge paths to decide if two physically contiguous bvec segments can be coalesced into one. It currently h...
CVE-2026-46115
In the Linux kernel block subsystem, CVE-2026-46115 was addressed by adding a check so that zone_device_pages_have_same_pgmap() prevents merging bvec segments that span different dev_pagemaps in biovec_phys_mergeable. Root cause: biovec_phys_mergeable() did not verify that two physically contiguo...

Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: block/rqqos: Protect the rqqos API with a new lock. The commit number is 50e34d78815e “block: disable the elevator int delgendisk”. The function rqqosexit was moved from diskrelease to delgendisk. This may introduce some issue...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: block: Fixed a potential deadlock in blkiarangesysfsshow When reading a sysfs attribute, the attribute is already protected against removal due to the active reference counter of the kobject node. As a result, in...
Linux kernel Block Buffer Overflow DoS
The vulnerability of the blkregisterqueue function in the block/blk-sysfs.c module, which is part of the Linux kernel’s block-level support, relates to the absence of memory release after the effective lifespan of the function has ended. Exploiting this vulnerability could allow an attacker to...
USN-8185-1: Linux kernel (NVIDIA) vulnerabilities
Josh Eads, Kristoffer Janke, Eduardo Vela Nava, Tavis Ormandy, and Matteo Rizzo discovered that some AMD Zen processors did not properly verify the signature of CPU microcode. This flaw is known as EntrySign. A privileged attacker could possibly use this issue to cause load malicious CPU microcod...
Linux kernel Block Buffer Overflow DoS
The vulnerability of the blkunregisterqueue function in the block/blk-sysfs.c module, which supports the block-level kernel in the Linux operating system, is related to code errors. Exploiting this vulnerability could allow an attacker to cause a service failure...
USN-8016-1 linux-nvidia, linux-nvidia-6.8, linux-nvidia-lowlatency 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: - Cryptographic API; - SPI subsystem; - SMB network file system; - iouring subsystem; CVE-2025-38561, CVE-2025-39698,...
CVE-2025-68807 block: fix race between wbt_enable_default and IO submission
In the Linux kernel, the following vulnerability has been resolved: block: fix race between wbtenabledefault and IO submission When wbtenabledefault is moved out of queue freezing in elevatorchange, it can cause the wbt inflight counter to become negative -1, leading to hung tasks in the writebac...
