This affects the function logicvc_drm_config_parse of the component logicvc. This manipulation causes memory leak. The identification of this vulnerability is CVE-2026-23426. There is no exploit available. The affected component should be upgraded. Detailsinfo A vulnerability has been found in Linux Kernel up to 7.0-rc1 and classified as critical. Affected by this vulnerability is the function logicvc_drm_config_parse of the component logicvc. The manipulation with an unknown input leads to a memory leak vulnerability. The CWE definition for the vulnerability is CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. As an impact it is known to affect availability. The summary by CVE is: In the Linux kernel, the following vulnerability has been resolved: drm/logicvc: Fix device node reference leak in logicvc_drm_config_parse() The logicvc_drm_config_parse() function calls of_get_child_by_name() to find the "layers" node but fails to release the reference, leading to a device node reference leak. Fix this by using the __free(device_node) cleanup attribute to automatic release the reference when the variable goes out of scope. It is possible to read the advisory at git.kernel.org. This vulnerability is known as CVE-2026-23426 since 01/13/2026. Technical details of the vulnerability are known, but there is no available exploit. Upgrading to version 6.1.167, 6.6.130, 6.12.77, 6.18.17, 6.19.7 or 7.0-rc2 eliminates this vulnerability. Applying the patch b88f49910be147b7974098b9172b0d3873142d6a/0bd326dffd9e103335d77d9c31275c0d5a7979eb/871630255ecd2d9b64ad1d75a7dfc0567d7d9989/f8a6eba20edb938166b26e133cc61306e1bc6de9/78e91e49d28e05ccaa6b445bafb5e367d57c9583/fef0e649f8b42bdffe4a916dd46e1b1e9ad2f207 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.
