Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: PCI: Endpoint: pci-epf-test: Add a NULL check for DMA channels before releasing them. The fields dmachantx and dmachanrx of the struct pciepftest can be NULL even after EPF initialization. Therefore, it is prudent to check that...

The vulnerabilities of the functions pci_epf_test_set_bar() and pci_epf_test_free_space() in the driver/drivers/pci/endpoint/functions/pci-epf-test.c file of the Linux operating system’s PCI kernel device driver allow an attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerabilities of the functions pciepftestsetbar and pciepftestfreespace in the driver/drivers/pci/endpoint/functions/pci-epf-test.c file of the Linux kernel’s PCI driver module are related to the reallocation of previously freed memory. Exploiting these vulnerabilities could allow an attack...
