CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Summaryinfo

A vulnerability marked as critical has been reported in Linux Kernel up to 6.12.96/6.18.39/7.1.4/7.2-rc2. This issue affects the function v3d_get_cpu_indirect_csd_params of the file drm/v3d of the component v3d. Performing a manipulation of the argument handle results in null pointer dereference. This vulnerability was named CVE-2026-72327. The attack may be initiated remotely. There is no available exploit.

Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel up to 6.12.96/6.18.39/7.1.4/7.2-rc2. This affects the function v3d_get_cpu_indirect_csd_params of the file drm/v3d of the component v3d. The manipulation of the argument handle with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Reject invalid indirect BO handle in indirect CSD setup v3d_get_cpu_indirect_csd_params() looks up the indirect buffer object from a userspace-supplied handle but never checks the result. A bogus or stale handle makes drm_gem_object_lookup() return NULL, which is then stored in info->indirect and only dereferenced later when the indirect CSD job runs, turning a userspace mistake into a NULL pointer dereference in the kernel. Bail out with -ENOENT as soon as the lookup fails, so the bad handle is rejected at submission time.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2026-72327 since 08/09/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. It demands that the victim is doing some kind of user interaction. 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 08/15/2026).

Upgrading to version 6.12.97, 6.18.40, 7.1.5 or 7.2-rc3 eliminates this vulnerability. Applying the patch 7c27f630dc78b673e136cab7d410399a1c52146a/762116dfa72865c82151970960f7cf34f44b21c8/5d65dade4d84913d1879f3db6a12ac007e08314b/2f8b8593c7832fad655290cef9e99af05b1b52b3 is able to eliminate this problem.
