kernel: Linux kernel: Denial of Service in ATM CLIP module via infinite recursion

A flaw was found in the Linux kernel's Asynchronous Transfer Mode ATM Classical IP CLIP module. A local user can trigger an infinite recursive call in the clippush function by repeatedly calling the ioctlATMARPMKIP system call. This vulnerability occurs when the socket is closed, leading to stack...

kernel: Linux kernel: Memory corruption in Squashfs due to incorrect block size calculation

A flaw was found in the Linux kernel's Squashfs filesystem. A local attacker can exploit this vulnerability by simultaneously mounting a Squashfs filesystem and issuing a specific input/output control ioctl command. This can lead to an incorrect block size calculation, causing a shift-out-of-boun...
