CVE-2026-45959

The CVE-2026-45959 issue affects the Linux kernel crypto: CCP driver. A local pointer annotated with __cleanup(kfree) could cause kfree to receive the local stack address instead of the allocated memory, leading to a crash. The underlying cause is incorrect cleanup usage; the repository indicates...

CVE-2026-45853 drm/amdgpu: Use kvfree instead of kfree in amdgpu_gmc_get_nps_memranges()

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Use kvfree instead of kfree in amdgpugmcgetnpsmemranges amdgpudiscoverygetnpsinfo internally allocates memory for ranges using kvcalloc, which may use vmalloc for large allocation. Using kfree to release vmalloc memor...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the failure of kmalloc when low memory conditions occur, resulting in the mutual locking mechanis...

PT-2026-43896

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description On Uniprocessor UP kernels where CONFIG SMP is not enabled, the spin trylock function acts as a no-op and unconditionally succeeds. This allows kmalloc nolock called from a Non-Maskable...

In the Linux kernel, the following vulnerability has been resolved: slab: Fixed the context check for kmallocnolock in the PREEMPTRT kernel mode. In PREEMPTRT kernels, locallock acts as a sleeping lock. The current check in kmallocnolock only verifies that the context does not match NMI or hardIR...

In the Linux kernel, the following vulnerability has been resolved: The tty function causes a deadlock when calling printk, under the ttyport-lock condition. The ptywrite function invokes kmalloc, which may also invoke a normal printk to print failure messages. This can lead to a deadlock in the...
