Detailsinfo

A vulnerability was found in Linux Kernel up to 6.12.100/6.18.41/7.1.4/7.2-rc2 and classified as very critical. This issue affects an unknown part of the component gpu-buddy. The manipulation with an unknown input leads to a allocation of resources vulnerability. Using CWE to declare the problem leads to CWE-770. The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: gpu/buddy: bail out of try_harder when alignment cannot be honoured The try_harder contiguous fallback could return a range whose start offset did not match the caller's min_block_size. When a candidate's start is misaligned, realign it: free the misaligned run and reallocate exactly @size at the next lower min_block_size boundary. This keeps the returned size unchanged with no surplus to trim, and rejects the request only when no aligned candidate fits. v2: align misaligned candidates down to min_block_size instead of bailing out, for both the RHS and LHS paths (Matthew).

It is possible to read the advisory at git.kernel.org. The identification of this vulnerability is CVE-2026-72244 since 08/09/2026. The exploitation is known to be easy. The attack may be initiated remotely. The technical details are unknown and an exploit is not publicly available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/15/2026). The attack technique deployed by this issue is T1499 according to MITRE ATT&CK.

Upgrading to version 6.12.101, 6.18.42, 7.1.5 or 7.2-rc3 eliminates this vulnerability. Applying the patch 4289531106ee175a6eb45db7d4f2734d1dae9887/7185c5262435b93e5eeffa647008992256b9c51a/419d7d9306491f3e0e417cf794844c73cabee090/56bc6384314fb9ae98975fb2af8b143097ede3dc is able to eliminate this problem.
