kernel: drivers/net/cxgb3/cxgb3_main.c reading uninitialized stack memory

The cxgbextensionioctl function in drivers/net/cxgb3/cxgb3main.c in the Linux kernel before 2.6.36-rc5 does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a CHELSIOGETQSETNUM ioctl call...

CVE-2010-3437

Integer signedness error in the pktfinddevfromminor function in drivers/block/pktcdvd.c in the Linux kernel before 2.6.36-rc6 allows local users to obtain sensitive information from kernel memory or cause a denial of service invalid pointer dereference and system crash via a crafted index value i...

Integer overflow

Multiple integer overflows in the sndctlnew function in sound/core/control.c in the Linux kernel before 2.6.36-rc5-next-20100929 allow local users to cause a denial of service heap memory corruption or possibly have unspecified other impact via a crafted 1 SNDRVCTLIOCTLELEMADD or 2...

CVE-2010-2537

CVE-2010-2537 affects the Linux kernel’s btrfs_ioctl_clone path: the btrfs_ioctl_clone function in fs/btrfs/ioctl.c before 2.6.35 allows a local attacker to overwrite an append‑only file when using BTRFS_IOC_CLONE or BTRFS_IOC_CLONE_RANGE with a donor file. Impact is local privilege/unauthorized ...

CVE-2010-2538

CVE-2010-2538: Integer overflow in btrfs_ioctl_clone (fs/btrfs/ioctl.c) of the Linux kernel before 2.6.35 may allow local users to obtain sensitive information via BTRFS_IOC_CLONE_RANGE. Public references confirm impact on local privilege/user data exposure with no remote vector. Affected compone...
