linux linux kernel 2.6.19.7 vulnerabilities and exploits

(subscribe to this query)

The signal handling in the Linux kernel prior to 2.6.22, including 2.6.2, when running on PowerPC systems using HTX, allows local users to cause a denial of service via unspecified vectors involving floating point corruption and concurrency, related to clearing of MSR bits.

fs/nfs/client.c in the Linux kernel prior to 2.6.23 does not properly initialize a certain structure member that stores the maximum NFS filename length, which allows local users to cause a denial of service (OOPS) via a long filename, related to the encode_lookup function.

The sctp_rcv_ootb function in the SCTP implementation in the Linux kernel prior to 2.6.23 allows remote malicious users to cause a denial of service (infinite loop) via (1) an Out Of The Blue (OOTB) chunk or (2) a chunk of zero length.

VFS in the Linux kernel prior to 2.6.22.16, and 2.6.23.x prior to 2.6.23.14, performs tests of access mode by using the flag variable instead of the acc_mode variable, which might allow local users to bypass intended permissions and remove directories.

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 sys_remap_file_pages function in mm/fremap.c in the Linux kernel prior to 2.6.24.1 allows local users to cause a denial of service or gain privileges via unspecified vectors, related to the vm_file structure member, and the mmap_region and do_munmap functions.
