In the Linux kernel, the following vulnerability has been resolved: ASoC: sti: use managed regmapfield allocations The regmapfield objects allocated at player init are never freed and may leak resources if the driver is removed. Switch to devmregmapfieldalloc to automatically limit the lifetime o...

CVE-2026-53042

In CVE-2026-53042, the Linux kernel vulnerability stems from an initialization order: CXL is linked before fwctl in drivers/Makefile, causing fwctl_register to run before fwctl_init, so fwctl_class isn’t registered when device_add is called. This makes class_to_subsys() return NULL, skipping knod...

EUVD-2026-38910

In the Linux kernel, the following vulnerability has been resolved: fwctl: Fix class init ordering to avoid NULL pointer dereference on device removal CXL is linked before fwctl in drivers/Makefile. Both use moduleinit, so cxlpcidriverinit runs first. When cxlpciprobe calls fwctlregister and then...
