linux linux kernel 2.6.21.6 vulnerabilities and exploits

(subscribe to this query)

NA

mm/shmem.c in the Linux kernel prior to 2.6.28-rc3, when strict overcommit is enabled, does not properly handle the export of shmemfs objects by knfsd, which allows malicious users to cause a denial of service (NULL pointer dereference and knfsd crash) or possibly have unspecifie...

NA

The pci_register_iommu_region function in arch/sparc/kernel/pci_common.c in the Linux kernel prior to 2.6.29 on the sparc64 platform allows local users to cause a denial of service (system crash) by reading the /proc/iomem file, related to uninitialized pointers and the request_r...

1 EDB exploit

NA

The bdx_ioctl_priv function in the tehuti driver (tehuti.c) in Linux kernel 2.6.x prior to 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.

NA

The __qdisc_run function in net/sched/sch_generic.c in the Linux kernel prior to 2.6.25 on SMP machines allows local users to cause a denial of service (soft lockup) by sending a large amount of network traffic, as demonstrated by multiple simultaneous invocations of the Netperf ...

1 EDB exploit

NA

Buffer overflow in fs/cifs/connect.c in CIFS in the Linux kernel 2.6.29 and previous versions allows remote malicious users to cause a denial of service (crash) via a long nativeFileSystem field in a Tree Connect response to an SMB mount request.

NA

The (1) agp_generic_alloc_page and (2) agp_generic_alloc_pages functions in drivers/char/agp/generic.c in the agp subsystem in the Linux kernel prior to 2.6.30-rc3 do not zero out pages that may later be available to a user-space process, which allows local users to obtain sensit...

NA

The swiotlb functionality in the r8169 driver in drivers/net/r8169.c in the Linux kernel prior to 2.6.27.22 allows remote malicious users to cause a denial of service (IOMMU space exhaustion and system crash) by using jumbo frames for a large amount of network traffic, as demonst...

1 EDB exploit

NA

The __inet6_check_established function in net/ipv6/inet6_hashtables.c in the Linux kernel prior to 2.6.29, when Network Namespace Support (aka NET_NS) is enabled, allows remote malicious users to cause a denial of service (NULL pointer dereference and system crash) via vectors in...
