A vulnerability has been discovered in the Linux kernel. It has been classified as problematic. The affected function is nilfsnew inode in the file fs/nilfs2/inode.c of the BPF component. This vulnerability allows for manipulation after the memory allocation function free is called. The attack ca...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: PCI: Endpoint: pci-epf-vntb: Remove duplicate resource teardown The epfntbepcdestroy function duplicates the teardown that the caller is supposed to perform later. This leads to an error when .allowlink fails, or when .droplink i...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: cleanup of FB if dpuformatpopulatelayout fails If dpuformatpopulatelayout fails, then FB is prepared, but not cleaned up. This results in the pincount being leaked from the GEM object, causing a crash during DRM file...

A flaw was discovered in the Linux kernel’s Traffic Control TC subsystem. Using a specific networking configuration—redirecting egress packets to ingress using the TC “mirred” action—a local unprivileged user could trigger a CPU soft lockup ABBA deadlock when the transport protocol in use TCP or...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

A race condition was detected in the Linux kernel’s watch queue due to a missing lock in the piperesizering function. The specific flaw lies in the handling of pipe buffers. The problem arises from the lack of proper locking when performing operations on an object. This flaw allows a local user t...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: powerpc/64s: Fixed the program check interrupt emergency stack path issue. The emergency stack path was jumping into a 3: label within the GENCOMMONBODY macro for the normal path after it had finished, rather than jumping over...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

A flaw was discovered in the Linux kernel. A denial-of-service attack may occur if a consecutive request for NVMEIOCTLRESET and NVMEIOCTLSUBSYSRESET is made through the device file of the driver, resulting in a disconnection of the PCIe link...
