Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: igc: Fixed use-after-free errors during reset. The next descriptor to be watched nexttowatch is cleared when cleaning the TX ring. Failure to do this can lead to invalid memory accesses. If igcpoll runs while the controller is...

In the Linux kernel, the following vulnerability has been resolved: net: sxgbe: free TX rings on RX allocation failure When RX descriptor ring allocation fails, init dma desc rings only frees the partially allocated RX rings and returns. The TX rings that were allocated earlier in the same functi...

CVE-2026-45995 io_uring/zcrx: fix user_struct uaf

In the Linux kernel, the following vulnerability has been resolved: iouring/zcrx: fix userstruct uaf iofreerbufring usees a struct userstruct, which iozcrxifqfree puts it down before destroying the ring...

The vulnerability of the __cpu_map_ring_cleanup() function in the kernel/bpf/cpumap.c module, which is part of the Linux operating system’s BPF interpreter support, allows a malicious actor to cause a service failure.

The vulnerability of the cpumapringcleanup function in the kernel/bpf/cpumap.c module, which is part of the Linux kernel’s BPF interpreter support, is related to incorrect code validation for function return operations. Exploiting this vulnerability could allow an attacker to trigger a system...

CVE-2023-53660

The CVE describes a Linux kernel issue in the bpf/cpumap path where ptr_ring cleanup does not correctly handle skb-mode SKBs as XDP frames, causing incorrect memory-type usage warnings when xdp_redirect_cpu runs with skb-mode and stress-mode. The root cause, per the Astra Linux advisory, is twofo...

DEBIAN-CVE-2021-47105

In the Linux kernel, the following vulnerability has been resolved: ice: xsk: return xsk buffers back to pool when cleaning the ring Currently we only NULL the xdpbuff pointer in the internal SW ring but we never give it back to the xsk buffer pool. This means that buffers can be leaked out of th...
