Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel: Buffer overflow in the hfsplus_find_cat function in fs/hfsplus/catalog.c in the Linux kernel before 2.6.28-rc1 allows attackers to cause a denial of service via an hfsplus filesystem image with an invalid catalog namelength field, related to the hfsplus_cat_build_key_uni function. The hfsplus_block_allocate function in fs/hfsplus/bitmap.c in the Linux kernel before 2.6.28-rc1 does not check a certain return value from the read_mapping_page function before calling kmap, which allows attackers to cause a denial of service via a crafted hfsplus filesystem image. The __scm_destroy function in net/core/scm.c in the Linux kernel 2.6.27.4, 2.6.26, and earlier makes indirect recursive calls to itself through calls to the fput function, which allows local users to cause a denial of service via vectors related to sending an SCM_RIGHTS message through a UNIX domain socket and closing file descriptors. Additionaly, support for a broadcom bluetooth dongle was added to btusb driver, an eeepc shutdown hang caused by snd-hda-intel was fixed, a Realtek auto-mute bug was fixed, the pcspkr driver was reenabled, an acpi brightness setting issue on some laptops was fixed, sata_nv driver bugs were fixed, horizontal mousewheel scrolling with Logitech V150 mouse was fixed, and more. Check the changelog and related bugs for more details. This kernel also fixes the driver for Intel G45/GM45 video chipsets, in a way requiring also an updated Xorg driver, which is also being provided in this update
