>> Linux Kernel Multiple Denial of Service and Privilege Escalation Issues
|
Multiple vulnerabilities were identified in Linux Kernel, which could be exploited by malicious users to cause a denial of service and potentially obtain elevated privileges.
The first issue is due to an error in "mm/mempolicy.c" when handling policy system calls, which could be exploited by local attackers to cause a denial of service via a "set_mempolicy" call with a 0 bitmask.
The second flaw is due to a one-byte buffer overrun error in "kernel/sysctl.c" when processing an overly long user-supplied string, which could be exploited by local attackers to potentially execute arbitrary commands.
The third vulnerability is due to an error in "net/ipv4/fib_frontend.c" when processing malformed "fib_lookup" netlink messages, which could cause illegal memory references.
The fourth issue is due to a buffer overflow error in the CA-driver for TwinHan DST Frontend/Card [drivers/media/dvb/bt8xx/dst_ca.c], which could be exploited by malicious users to cause a denial of service or potentially execute arbitrary commands.
