Astra Linux – Vulnerability in xorg-server

A vulnerability was discovered in X.Org. This security flaw arises because the XkbCopyNames function left a dangling pointer pointing to freed memory, allowing for out-of-bounds memory access during subsequent XkbGetKbdByName requests. This issue can lead to local privileges escalation on systems...

Astra Linux – Vulnerability in Linux

In the rbd block device driver located in drivers/block/rbd.c within the Linux kernel, up to version 5.8.9, incomplete permission checks were used for accessing rbd devices. This could have been exploited by local attackers to map or unmap rbd block devices, specifically the CID-f44d04e696fe devi...

In the Linux kernel, the following vulnerabilities have been resolved: ARM: footbridge: fixed PCI interrupt mapping Since commit 30fdfb929e82 "PCI: added a call to pciassignirq in pcideviceprobe", the PCI code will call the IRQ mapping function whenever a PCI driver is probed. If these functions...

Astra Linux – Vulnerability in Linux, Linux 5.10

A memory leak flaw in the Linux kernel’s hugetlbfs memory usage was discovered in the way that the system maps some regions of memory twice using shmget. These mappings are aligned according to PUD alignment, resulting in some memory pages being misaligned. A local user could exploit this flaw to...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: x86/ioremap: Maps EFI-reserved memory as encrypted for SEV. Some drivers require memory that is marked as EFI boot services data. To prevent this memory from being reused by the kernel after ExitBootServices, efimemreserve is use...

Astra Linux – Vulnerability in Samba

A flaw was discovered in Samba. The Samba smbd file server must map Windows group identities SIDs to Unix group IDs gids.
