Astra Linux – Vulnerability in Linux, Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: proc/vmcore: The issue of clearing the user buffer was fixed by properly using clearuser. To clear a user buffer, we cannot simply use memset; we must use clearuser. When using a virtio-mem device that registers a vmcorecb and ha...

Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: x86/fpu: The FPU state is invalidated after a failed XRSTOR operation from a user buffer. Both Intel and AMD consider it to be architecturally valid for XRSTOR to fail with PF, but they have nonetheless changed the state of the...
CVE-2026-64293
A flaw was found in the Linux kernel's iommufd component. This vulnerability arises from an incorrect size calculation during a bound-check in the iommufdveventqfopsread function. On 32-bit systems, this error can lead to an out-of-bounds write, allowing data to be copied past the intended...
The vulnerability of the tee_shm_register_user_buf() function in the drivers/tee/tee_shm.c module of the Linux kernel’s trusted execution environment allows a attacker to cause a service failure.
The vulnerability of the teeshmregisteruserbuf function in the drivers/tee/teeshm.c module of the Linux kernel’s trusted execution environment is related to pointer manipulation. Exploiting this vulnerability could allow an attacker to cause a service failure...
