Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: schcake: A out-of-bounds access issue was fixed during the parsing of TCP options and headers. The TCP option parser in cake qdisc cakegettcpopt and caketcphmaydrop could read one byte out of bounds. When the length of the data...

PT-2026-79709

In the Linux kernel, the following vulnerability has been resolved: net/sched: sch cake: drop WARN ON1 for malformed packets in ACK filter The sch cake ACK filter parses packets to find the TCP header and filter duplicated ACKs if the flow is backlogged. The parsing code contains a WARN ON1 which...

CVE-2026-72326

A flaw was found in the Linux kernel's CAKE Common Applications Kept Enhanced packet scheduler. This vulnerability arises from the incorrect handling of signed overhead values, which can lead to an integer underflow during packet length calculations. A negative effective length can then wrap to a...

CVE-2026-72326

CVE-2026-72326 affects the Linux kernel’s net/sched cake scheduler. CAKE accepts signed overhead values stored in an s16, but the adjusted packet length calculation uses unsigned arithmetic, allowing a negative effective length to wrap to a large value. This can cause rate accounting to depend on...
