DescriptionNVD

In the Linux kernel, the following vulnerability has been resolved:

reset: amlogic: t7: Fix null reset ops

Fix missing reset ops causing kernel null pointer dereference. This SOC's reset is currently not used yet.

AnalysisAI

Null pointer dereference in the Amlogic T7 SoC reset driver crashes the Linux kernel when uninitialized reset operation callbacks are invoked, causing a full system denial of service. Local low-privilege users on systems physically equipped with an Amlogic T7 SoC are affected across kernel versions from the introduction commit through the patched releases 6.18.33, 7.0.10, and 7.1. No public exploit has been identified and EPSS of 0.17% (6th percentile) reflects negligible real-world exploitation interest; this is a hardware-specific stability fix rather than an actively exploited security threat.

Technical ContextAI

The vulnerability resides in the Linux kernel reset controller subsystem, specifically the Amlogic T7 SoC driver under drivers/reset/amlogic/t7. CWE-476 (NULL Pointer Dereference) identifies the root cause: the driver registers with the kernel reset framework without initializing the required reset_ops structure. When any kernel path dereferences this ops pointer - such as during subsystem initialization or device probe - the kernel encounters a NULL address and panics. The upstream commit description explicitly states the T7 SoC reset is currently unused, meaning the vulnerable code path may be latent in most deployments and not readily exercised without specific hardware activity. Affected code is introduced at commit fb4c31587adfa9cd50661a535bdbfcc4da57ee38 and spans multiple stable branches. CPE identifier cpe:2.3:a:linux:linux covers the affected software, while the practical scope is restricted entirely to physical Amlogic T7 SoC hardware.

RemediationAI

Upgrade to a patched kernel version: 6.18.33 or later in the 6.18.x series, 7.0.10 or later in the 7.0.x series, or kernel 7.1 or later for mainline. The three upstream fix commits are available at https://git.kernel.org/stable/c/cde69482d2e6834dcd4ed675d1ef84e48627ee9f, https://git.kernel.org/stable/c/463a0885de665d3f36e219c5502584b99fa61c85, and https://git.kernel.org/stable/c/9797524ef2b69c6b187b55bd844eb72a8c1cbd99. Distribution maintainers (Debian, Ubuntu, RHEL, etc.) may backport the fix to their respective stable kernels; check vendor security channels. As a compensating control, since the upstream description confirms the T7 reset subsystem is currently unused, systems that do not exercise this driver path have reduced practical exposure - however, applying the kernel patch remains the only definitive remediation.
