ROS-20260923-73-0068

The vulnerability in the mm/kmsan/core.c and mm/kmsan/kmsantest.c modules of the Linux operating system relates to the execution of operations beyond the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to cause a service failure...

kernel: mm/slab: do not limit zeroing to orig_size when only red zoning is enabled

A flaw was found in the Linux kernel's memory management subsystem. This issue occurs when the kernel's memory allocator attempts to zero out newly allocated memory, but an incorrect check prevents the full memory region from being cleared under specific configurations. This can lead to memory no...
