Mandriva Linux Security Advisory - Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel package.
a22bc116b2abbe7adc279c9653623c50268cacda2c1139b16c87517248f69822Mandriva Linux Security Advisory - The bdx_ioctl_priv function in the tehuti driver (tehuti.c) in Linux kernel 2.6.x before 2.6.25.1 does not properly check certain information related to register size, which has unspecified impact and local attack vectors, probably related to reading or writing kernel memory. Additionally, some fixes were made, related to: iwlwifi (small bug interacting with drakconnect interface detection), brightness handling on EeePc, uvcvideo on Thinkpad X300, sound for TOSHIBA Satellite Pro A200 and A210, RealTek 8169 ethernet, unionfs, and more.
e2c7f9ca31e1a830b26d32bb28c2e8bd202c4a3b98b402586a4f6a9c2ef72fb1Ubuntu Security Notice 614-1 - It was discovered that PowerPC kernels did not correctly handle reporting certain system details. By requesting a specific set of information, a local attacker could cause a system crash resulting in a denial of service. A race condition was discovered between dnotify fcntl() and close() in the kernel. If a local attacker performed malicious dnotify requests, they could cause memory consumption leading to a denial of service, or possibly send arbitrary signals to any process. On SMP systems, a race condition existed in fcntl(). Local attackers could perform malicious locks, causing system crashes and leading to a denial of service. The tehuti network driver did not correctly handle certain IO functions. A local attacker could perform malicious requests to the driver, potentially accessing kernel memory, leading to privilege escalation or access to private system information.
