Detailsinfo

A vulnerability has been found in Linux Kernel up to 6.14.1 and classified as critical. Affected by this vulnerability is the function mvpp2_set_rx_mode. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: net: mvpp2: Prevent parser TCAM memory corruption Protect the parser TCAM/SRAM memory, and the cached (shadow) SRAM information, from concurrent modifications. Both the TCAM and SRAM tables are indirectly accessed by configuring an index register that selects the row to read or write to. This means that operations must be atomic in order to, e.g., avoid spreading writes across multiple rows. Since the shadow SRAM array is used to find free rows in the hardware table, it must also be protected in order to avoid TOCTOU errors where multiple cores allocate the same row. This issue was detected in a situation where `mvpp2_set_rx_mode()` ran concurrently on two CPUs. In this particular case the MVPP2_PE_MAC_UC_PROMISCUOUS entry was corrupted, causing the classifier unit to drop all incoming unicast - indicated by the `rx_classifier_drops` counter.

The advisory is shared at git.kernel.org. This vulnerability is known as CVE-2025-22060 since 12/29/2024. The exploitation appears to be easy. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 02/15/2026).

The vulnerability scanner Nessus provides a plugin with the ID 234884 (Debian dsa-5907 : affs-modules-6.1.0-33-4kc-malta-di - security update), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 5.15.180, 6.1.134, 6.6.87, 6.12.23, 6.13.11, 6.14.2 or 6.15-rc1 eliminates this vulnerability. Applying the patch e3711163d14d02af9005e4cdad30899c565f13fb/b3f48a41a00d6d8d9c6fe09ae47dd21c8c1c8b03/5b0ae1723a7d9574ae1aee7d9cf9757a30069865/fcbfb54a0269875cf3cd6a2bff4f85a2e0a0b552/e64e9b6e86b39db3baa576fd73da73533b54cb2d/46c1e23e34c9d1eaadf37f88216d9d8ce0d0bcee/96844075226b49af25a69a1d084b648ec2d9b08d is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.

The vulnerability is also documented in the databases at Tenable (234884) and CERT Bund (WID-SEC-2025-0844). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
