SUSE CVE-2026-53058

In the Linux kernel, the following vulnerability has been resolved: drm/bridge: cadence: cdns-mhdp8546-core: Set the mhdp connector earlier in atomicenable In case if we get errors in cdnsmhdplinkup or cdnsmhdpregread in atomicenable, we will go to cdnsmhdpmodesetretryfn and will hit NULL pointer...

CVE-2026-53058

A flaw was found in the drm/bridge: cadence: cdns-mhdp8546-core component of the Linux kernel. This vulnerability allows for a NULL pointer dereference during error handling within the atomicenable function. If cdnsmhdplinkup or cdnsmhdpregread encounter errors, a subsequent attempt to access a...

CVE-2026-53058

CVE-2026-53058 affects the Linux kernel DRM Cadence CDNS-MHDP8546 core in atomic_enable paths. The fault occurs when errors in cdns_mhdp_link_up() or cdns_mhdp_reg_read() cause a NULL pointer in modeset_retry_fn() because the connector isn’t initialised. The fix adds a connector_ptr to the mhdp d...

PT-2026-51952

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A NULL pointer dereference can occur in the recovery paths of the cadence cdns-mhdp8546-core driver. When errors occur in the cdns mhdp link up or cdns mhdp reg read functions during...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/client: Do not destroy NULL modes. The modes in drcmclientmodesetprobe may fail to be allocated using kcalloc. If this occurs, we jump to out, and modesDestroy is called on it. This action will dereference modes. This could...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: drm/client: Fixed a memory leak in drmclientmodesetprobe. When a new mode is set to modeset-mode, the previous mode should be freed. This fixes the following kmemleak reports: drmmodeduplicate+0x45/0x220 drm...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: Added a null pointer check for dpuencoderneedsmodeset. The drmatomicgetnewconnectorstate function may return NULL if the connector is not part of the atomic state. A check was added to prevent a NULL pointer...

The vulnerability in the function `drcm_client_modeset_probe()` of the `drivers/gpu/drm/drm_client_modeset.c` file, a part of the Direct Rendering Infrastructure (DRI) driver for the Linux operating system, allows a hacker to cause a service failure.

The vulnerability of the drmclientmodesetprobe function in the drivers/gpu/drm/drmclientmodeset.c file of the Direct Rendering Infrastructure DRI driver module in the Linux operating system is related to improper memory release memory leak. Exploiting this vulnerability could allow an attacker to...

SUSE CVE-2026-23366

In the Linux kernel, the following vulnerability has been resolved: drm/client: Do not destroy NULL modes 'modes' in drmclientmodesetprobe may fail to kcalloc. If this occurs, we jump to 'out', calling modesdestroy on it, which dereferences it. This may result in a NULL pointer dereference in the...

CVE-2026-23366

A flaw was found in the Linux kernel's Direct Rendering Manager DRM client component. This vulnerability occurs when the system attempts to destroy an uninitialized memory pointer, specifically the 'modes' variable within the drmclientmodesetprobe function, after a memory allocation failure. This...
