CVE-2025-40196

CVE-2025-40196 concerns the Linux kernel quota subsystem. A writeback-triggered flush could trigger a kernel panic due to MEM_RECLAIM flag mismatch when quota_release_work runs on the non MEM_RECLAIM queue. The patch adds a dedicated workqueue with the WQ_MEM_RECLAIM flag for quota_release_work t...

CVE-2025-40188

CVE-2025-40188 affects the Linux kernel PWM Berlin driver. The root cause is an incorrect register being used during suspend/resume: the code writes to BERLIN_PWM_ENABLE instead of BERLIN_PWM_EN, causing the driver to access the wrong address. This misaccess leads to a CPU exception and kernel pa...
