linux linux kernel 2.6.22.20 vulnerabilities and exploits

(subscribe to this query)

The __nfs4_proc_set_acl function in fs/nfs/nfs4proc.c in the Linux kernel prior to 2.6.38 stores NFSv4 ACL data in memory that is allocated by kmalloc but not properly freed, which allows local users to cause a denial of service (panic) via a crafted attempt to set an ACL.

Integer overflow in the _ctl_do_mpt_command function in drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel 2.6.38 and previous versions might allow local users to gain privileges or cause a denial of service (memory corruption) via an ioctl call specifying a crafted value tha...

drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel 2.6.38 and previous versions does not validate (1) length and (2) offset values before performing memory copy operations, which might allow local users to gain privileges, cause a denial of service (memory corruption), or obt...

Heap-based buffer overflow in the is_gpt_valid function in fs/partitions/efi.c in the Linux kernel 2.6.38 and previous versions allows physically proximate malicious users to cause a denial of service (OOPS) or possibly have unspecified other impact via a crafted size of the EFI ...

The parisc_show_stack function in arch/parisc/kernel/traps.c in the Linux kernel prior to 2.6.28-rc7 on PA-RISC allows local users to cause a denial of service (system crash) via vectors associated with an attempt to unwind a stack that contains userspace addresses.

mm/shmem.c in the Linux kernel prior to 2.6.28-rc8, when strict overcommit is enabled and CONFIG_SECURITY is disabled, 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 cr...

The virtio_net_bad_features function in hw/virtio-net.c in the virtio-net driver in the Linux kernel prior to 2.6.26, when used on a guest OS in conjunction with qemu-kvm 0.11.0 or KVM 83, allows remote malicious users to cause a denial of service (guest OS crash, and an associat...
