>> Linux Kernel Security Update Fixes Multiple Denial of Service Vulnerabilities
|
|
Multiple vulnerabilities have been identified in Linux Kernel, which could be exploited by attackers or malicious users to cause a denial of service.
The first issue is due to a race condition error in the "posix-cpu-timers.c" script that does not prevent another CPU from attaching the timer to an exiting process, which could be exploited by attackers to cause a denial of service.
The second flaw is due to errors in "powerpc/kernel/signal_32.c" and "powerpc/kernel/signal_32.c", which could allow userspace to provoke a machine check on 32-bit kernels.
The third vulnerability is due to an infinite loop in "netfilter/xt_sctp.c", which could be exploited by attackers to exhaust all available memory resources, creating a denial of service condition.
