Some vulnerabilities have been reported in the Linux Kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service) and gain escalated privileges.
1) A vulnerability is caused due to an error within the driver for i965G chipsets and above, which can be exploited to e.g. gain escalated privileges by modifying physical memory.
Successful exploitation requires that the attacker is logged in to an X server and has access to the DRM.
2) A vulnerability is caused due to the "pipe_to_file()" function in fs/splice.c incorrectly unlocking a page if a call to "add_to_page_cache_lru()" fails, which can be exploited to crash a vulnerable system.
Solution: Update to version 126.96.36.199.
Provided and/or discovered by: 1) Reported by the vendor.
2) Reported in a bug by Gurudas Pai.
