CVE-2025-21980

In the Linux kernel, the following vulnerability has been resolved: sched: address a potential NULL pointer dereference in the GRED scheduler. If kzalloc in gredinit returns a NULL pointer, the code follows the error handling path, invoking greddestroy. This, in turn, calls gredoffload, where...

CVE-2025-21982

CVE-2025-21982 affects the Linux kernel’s pinctrl nuvoton npcm8xx GPIO firmware path. The issue stems from devm_kasprintf() potentially returning NULL on failure, with the NULL return not being checked in npcm8xx_gpio_fw(), leading to a kernel NULL pointer dereference. A fix adds a NULL-check in ...

CVE-2025-21980

The CVE-2025-21980 entry concerns the Linux kernel GRED scheduler. It covers a potential NULL pointer dereference when kzalloc in gred_init returns NULL and the error path leads to gred_destroy, which calls gred_offload and may pass a NULL pointer to memset, potentially crashing the kernel. The i...

CVE-2025-21944

CVE-2025-21944 concerns the ksmbd component of the Linux kernel, where a bug in trap handling for smb2_lock can occur if the lock count exceeds 1. The root cause is that the code checked flags from the wrong source (flags) instead of the flags of smb_lock, which may lead to an erroneous trap in t...

CVE-2025-21924

CVE-2025-21924 : In the Linux kernel, during ptp initialization for the hns3 driver, hclge_ptp_get_cycle may fail and previously not unregister/free the clock. The fix calls hclge_ptp_destroy_clock to unregister and free the clock when hclge_ptp_get_cycle fails, mitigating potential resource leaks.
