Linux privcmd driver can circumvent kernel lockdown
ISSUE DESCRIPTION The Linux kernel's privcmd driver can be abused to circumvent kernel lockdown secure boot, e.g. by modifying page tables to enable user mode to modify kernel memory. IMPACT An administrator of an unprivileged guest booted in secure mode is able to perform actions on the kernel...
Linux kernel device driver Heap Buffer Overflow DoS
The vulnerabilities of the functions lockpages and privcmdioctldmop in the drivers/xen/privcmd.c module of the Linux kernel device driver for page buffer management are related to the use of pointers. Exploiting these vulnerabilities could allow a remote attacker to cause service interruptions...
