linux linux kernel 2.6.30.9 vulnerabilities and exploits

(subscribe to this query)

The fuse_ioctl_copy_user function in the ioctl handler in fs/fuse/file.c in the Linux kernel 2.6.29-rc1 up to and including 2.6.30.y uses the wrong variable in an argument to the kunmap function, which allows local users to cause a denial of service (panic) via unknown vectors.

The btrfs_ioctl_clone function in fs/btrfs/ioctl.c in the btrfs functionality in the Linux kernel 2.6.29 up to and including 2.6.32, and possibly other versions, does not ensure that a cloned file descriptor has been opened for reading, which allows local users to read sensitive ...

The ip_frag_reasm function in net/ipv4/ip_fragment.c in the Linux kernel 2.6.32-rc8, and 2.6.29 and later versions prior to 2.6.32, calls IP_INC_STATS_BH with an incorrect argument, which allows remote malicious users to cause a denial of service (NULL pointer dereference and han...

arch/powerpc/mm/fsl_booke_mmu.c in KGDB in the Linux kernel 2.6.30 and other versions prior to 2.6.33, when running on PowerPC, does not properly perform a security check for access to a kernel page, which allows local users to overwrite arbitrary kernel memory, related to Fsl bo...

Linux kernel 2.6.18 up to and including 2.6.33, and possibly other versions, allows remote malicious users to cause a denial of service (memory corruption) via a large number of Bluetooth sockets, related to the size of sysfs files in (1) net/bluetooth/l2cap.c, (2) net/bluetooth/...

The fuse_direct_io function in fs/fuse/file.c in the fuse subsystem in the Linux kernel prior to 2.6.32-rc7 might allow malicious users to cause a denial of service (invalid pointer dereference and OOPS) via vectors possibly related to a memory-consumption attack.

Race condition in the mac80211 subsystem in the Linux kernel prior to 2.6.32-rc8-next-20091201 allows remote malicious users to cause a denial of service (system crash) via a Delete Block ACK (aka DELBA) packet that triggers a certain state change in the absence of an aggregation...

The collect_rx_frame function in drivers/isdn/hisax/hfc_usb.c in the Linux kernel prior to 2.6.32-rc7 allows malicious users to have an unspecified impact via a crafted HDLC packet that arrives over ISDN and triggers a buffer under-read.
