Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In nftablesupdtable, if nftablestableenable returns an error, nfttransdestroy is called to free the transaction object. nfttransDestroy calls listdel, but the transaction was never placed on a list—the list head contains only zeros, which results in a NULL pointer being dereferenced...

Astra Linux – Vulnerability in TIF format

A null pointer dereference flaw was detected in Libtiff through the tifdirinfo.c file. This issue may allow an attacker to trigger memory allocation failures through certain methods, such as restricting the heap space size or injecting faults, resulting in a segmentation fault. This can cause the...

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2, where the grubextcmddispatcher function calls grubarglistalloc to allocate memory for the grub’s argument list.
