CVE-2026-93820

A flaw was found in the Linux kernel's Rockchip PCIe host controller driver. Stopping and removing a PCIe root bus without proper synchronization creates a race condition with concurrent device rescanning or hotplug operations. A local attacker could exploit this flaw to cause a use-after-free...

CVE-2026-93818

A flaw was found in the Linux kernel's PLDA PCIe host controller driver. This vulnerability can result in a Denial of Service DoS caused by a race condition when removing a root bus without holding the required lock. A local user with administrative privileges can exploit this issue by triggering...

Astra Linux – Vulnerability in Qemu

A “off-by-one” read/write issue was identified in the SDHCI device of QEMU. This issue occurs when reading/writing the Buffer Data Port Register using the sdhcireaddataport and sdhciwritedataport functions, specifically when datacount == blocksize. A malicious guest could exploit this flaw to cra...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: xhci: Properly handling isoc Babble and Buffer Overrun events. xHCI 4.9 explicitly prohibits making assumptions that the xHC has released its ownership of a multi-TRB TD when an error occurs in one of the early TRBs. However,...

Astra Linux – Vulnerability in Qemu

A heap-based buffer overflow was discovered in the SDHCI device emulation of QEMU. The bug is triggered when both s-datacount and the size of s-fifobuffer are set to 0x200, leading to an out-of-bound access. A malicious guest could exploit this flaw to crash the QEMU process on the host, resultin...
