UBUNTU-CVE-2026-53237: Null Pointer Dereference

Published Jun 25, 2026

Updated

In the Linux kernel, the following vulnerability has been resolved: gpio: mvebu: fix NULL pointer dereference in suspend/resume mvebupwmsuspend() and mvebupwmresume() are called for all GPIO banks during suspend/resume, but not all banks have PWM functionality. GPIO banks without PWM have mvchip->mvpwm set to NULL. Calling mvebupwmsuspend() with mvpwm == NULL causes a NULL pointer dereference when it tries to access mvpwm->blinkselect. Unable to handle kernel NULL pointer dereference at virtual address 00000020 when write [00000020] pgd=00000000 Internal error: Oops: 815 [#1] PREEMPT ARM Modules linked in: CPU: 0 UID: 0 PID: 406 Comm: sh Not tainted 6.12.74-rt12-yocto-standard-g4e96f98fb7db-dirty #353 Hardware name: Marvell Armada 370/XP (Device Tree) PC is at regmapmmioread+0x38/0x54 LR is at regmapmmioread+0x38/0x54 pc : [<c05fd2ac>] lr : [<c05fd2ac>] psr: 200f0013 sp : f0c11d10 ip : 00000000 fp : c100d2f0 r10: c14fb854 r9 : 00000000 r8 : 00000000 r7 : c1799c00 r6 : 00000020 r5 : 00000020 r4 : c179c7c0 r3 : f0a231a0 r2 : 00000020 r1 : 00000020 r0 : 00000000 Flags: nzCv IRQs on FIQs on Mode SVC32 ISA ARM Segment none Control: 10c5387d Table: 135ec059 DAC: 00000051 Call trace: regmapmmioread from regmapbusregread+0x78/0xac regmapbusregread from regmapread+0x60/0x154 regmapread from regmapread+0x3c/0x60 regmapread from mvebugpiosuspend+0xa4/0x14c mvebugpiosuspend from dpmruncallback+0x54/0x180 dpmruncallback from devicesuspend+0x124/0x630 devicesuspend from dpmsuspend+0x124/0x270 dpmsuspend from dpmsuspendstart+0x64/0x6c dpmsuspendstart from suspenddevicesandenter+0x140/0x8e8 suspenddevicesandenter from pmsuspend+0x2fc/0x308 pmsuspend from statestore+0x6c/0xc8 statestore from kernfsfopwriteiter+0x10c/0x1f8 kernfsfopwriteiter from vfswrite+0x270/0x468 vfswrite from ksyswrite+0x70/0xf0 ksyswrite from retfastsyscall+0x0/0x54 Add a NULL check for mvchip->mvpwm before calling the PWM suspend/resume functions.

DescriptionSeverityAffected Software

Frequently Asked Questions

Which deployments are most relevant to this issue?

The issue is relevant to systems using the mvebu GPIO driver on Marvell Armada 370/XP Device Tree hardware, particularly where GPIO banks without PWM functionality are present. The listed Ubuntu kernel package families include linux, linux-aws-fips, linux-azure, linux-azure-fips, linux-fips, linux-gcp, linux-gcp-fips, and linux-oracle.

What condition triggers the failure?

The failure occurs during system suspend or resume when the PWM suspend/resume routines are called for a GPIO bank that has no PWM support. Such banks have a NULL mvpwm pointer, which is dereferenced while accessing blink_select.

What is the practical impact?

The documented outcome is a kernel NULL-pointer dereference and kernel Oops during suspend or resume. The CVSS vector indicates availability impact without confidentiality or integrity impact.

How can an administrator assess whether a system is exposed?

Confirm whether the system uses affected listed Ubuntu kernel package families on Marvell Armada 370/XP hardware with the mvebu GPIO driver, and whether it has GPIO banks lacking PWM functionality. A kernel Oops during suspend or resume with a NULL-pointer access in the mvebu PWM path is consistent with this issue.
