Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, if the IMA appraisal method is used with the “imaappraise=log” boot parameter, lockdown can be circumvented using kexec on any machine when Secure Boot is disabled or unavailable. IMA prevents the “imaappraise=log” parameter from being set during boot, but this does not cover...

Astra Linux – Vulnerability in grub2

A crafted 16-bit grayscale PNG image may lead to an out-of-bounds write in the heap area. An attacker may exploit this to cause heap data corruption or, ultimately, arbitrary code execution and circumvent secure boot protections. This issue is highly complex to exploit; an attacker needs to perfo...

In the Linux kernel, the following vulnerabilities have been resolved: fscrypt: fixed an underflow issue during left shift when inode-iblkbits PAGESHIFT When simulating an nvme device on qemu with both logicalblocksize and physicalblocksize set to 8 KiB, an error trace appears during partition...

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2 in versions prior to 2.06. The cutmem command does not honor secure boot locking, allowing a privileged attacker to remove address ranges from memory. This creates an opportunity to circumvent SecureBoot protections after proper analysis of grub’s memory layout. The...
