Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
A security issue and a vulnerability have been reported in the Linux Kernel, which potentially can be exploited by malicious, local users to cause a DoS (Denial of Service) or potentially gain escalated privileges.

1) The security is caused due to a NULL pointer dereference in arch/powerpc/platforms/chrp/setup.c, which can be exploited to crash a vulnerable system.

Successful exploitation requires certain PowerPC hardware.

2) The vulnerability is caused due to the "sys_remap_file_pages()" function in mm/fremap.c not properly accounting for certain variables. This can be exploited to e.g. crash the system or potentially gain escalated privileges.
