Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The (1) __futex_atomic_op and (2) futex_atomic_cmpxchg_inatomic functions in Linux kernel 2.6.17-rc4 to 2.6.18-rc2 perform the atomic futex operation in the kernel address space instead of the user address space, which allows local users to cause a denial of service (crash).


Remediation

Install update from vendor's repository.
