CVE-2026-53237

In CVE-2026-53237, the Linux kernel’s mvebu GPIO implementation can dereference a NULL mvchip->mvpwm during suspend/resume because mvebu_pwm_suspend() / mvebu_pwm_resume() are invoked for all GPIO banks, including those without PWM functionality. The root cause is that some banks have mvchip-&...

CVE-2026-53237 gpio: mvebu: fix NULL pointer dereference in suspend/resume

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-mvpw...

CVE-2026-53227

CVE-2026-53227 affects the Linux kernel net/openvswitch path. The issue arises when allocating the reply skb after taking ovs_mutex, where an error path can leave the skb with an ERR_PTR and later free it during cleanup, leading to a possible invalid free. The fix sets the pointer to NULL after s...

CVE-2026-53213

In the Linux kernel drm/vc4 component, CVE-2026-53213 is a memory-leak fix related to krealloc(): if krealloc() returns NULL, the original pointer may be overwritten, leaking memory. The recommended pattern is to assign krealloc() to a temporary variable, check for NULL, then update the original ...

CVE-2026-53204

The CVE-2026-53204 issue concerns the Linux kernel firmware for Stratix 10 RSU (rsu_send_msg timeout). When wait_for_completion_interruptible_timeout() times out while an SMC call is pending, rsu_send_msg() could lead to a NULL dereference in stratix10_rsu_probe() due to error-path handling that ...
