Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: locking/csdlock: The csdlockdebug parameter should be changed from earlyparam to setup. The csdlockdebug kernel-boot parameter is processed by the earlyparam function csdlockdebug. If this parameter is set, csdlockdebug invokes...

SUSE CVE-2026-64149

In the Linux kernel, the following vulnerability has been resolved: dma-mapping: move dmamapresource sanity check into debug code dmamapresource uses pfnvalid to ensure the range is not RAM. However, pfnvalid only checks for availability of the memory map for a PFN but it does not ensure that the...

kernel: mm/sparsemem: fix race in accessing memory_section->usage

A race condition was found on a PFN in the Linux Kernel, which can fall into the device memory region with the system memory configuration. Normal zone start and end PFNs contain the device memory PFNs as well, and the compaction triggered will try on the device memory PFNs and end up in NOP. Thi...
