CVE-2026-45926

CVE-2026-45926 concerns the Linux kernel PWM initialization. The memory leak occurs when pwmchip_alloc() allocates a pwm_chip and the initial reference isn’t released on all error paths if __pinned_init() fails, causing a leak and potential resource exhaustion. The connected documents confirm the...

CVE-2026-45922

In CVE-2026-45922, the Linux kernel RDMA/mlx5 GET_DATA_DIRECT_SYSFS_PATH handler leaks memory: it allocates device-path memory with kobject_get_path() and, if the path length exceeds the output buffer, returns -ENOSPC without freeing, causing a memory leak. The fix adds a kfree() in the error pat...
