CVE-2023-54264 concerns the Linux kernel, in the fs/sysv path, where a null pointer dereference could occur if sb_getblk(inode->i_sb, parent) returns NULL and a lock is taken on it. The connected advisories confirm the vulnerability and note that a fix was applied by adding a null check to pre...

CVE-2023-54249

The CVE concerns the Linux kernel component bus: mhi: ep. The issue arises when handling STOP and RESET commands: the system may send a -ENOTCONN status even if the client driver is not available, which could lead to a null pointer dereference. The available connected sources confirm this is a ke...
