kernel: bug in GFS/GFS2 locking code leads to dos

The gfs2lock function in the Linux kernel before 2.6.34-rc1-next-20100312, and the gfslock function in the Linux kernel on Red Hat Enterprise Linux RHEL 5 and 6, does not properly remove POSIX locks on files that are setgid without group-execute permission, which allows local users to cause a...

Linux Kernel 2.2.x<= 25 – 2.4.x<21 ptrace/kmod Local Root Exploit

No description provided by source. / Linux kernel ptrace/kmod local root exploit This code exploits a race condition in kernel/kmod.c, which creates kernel thread in insecure manner. This bug allows to ptrace cloned process, allowing to take control over privileged modprobe binary. Should work...

kernel: r8169 issue reported at 26c3

drivers/net/r8169.c in the r8169 driver in the Linux kernel 2.6.32.3 and earlier does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to 1 cause a denial of service temporary network outage via a packet with a crafted size, in conjunction with...

kernel: emergency route cache flushing leads to node deadlock

A certain Red Hat patch for net/ipv4/route.c in the Linux kernel 2.6.18 on Red Hat Enterprise Linux RHEL 5 allows remote attackers to cause a denial of service deadlock via crafted packets that force collisions in the IPv4 routing hash table, and trigger a routing "emergency" in which a hash chai...

kernel: nfsv4 client can be crashed by stating a long filename

fs/nfs/client.c in the Linux kernel before 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 encodelookup function...

Kernel BUG() in locks_remove_flock

Race condition in the dosetlk function in fs/nfs/file.c in the Linux kernel before 2.6.26 allows local users to cause a denial of service crash via vectors resulting in an interrupted RPC call that leads to a stray FLPOSIX lock, related to improper handling of a race between fcntl and close in th...

Race condition in the dosetlk function in fs/nfs/file.c in the Linux kernel before 2.6.26 allows local users to cause a denial of service crash via vectors resulting in an interrupted RPC call that leads to a stray FLPOSIX lock, related to improper handling of a race between fcntl and close in th...

MDVA-2009:045 : dhcp

dhclient-script, in dhcp-client package as released with Mandriva Linux 2009, would put the network interface down on some circumstances, as part of it's workings. Coupled with a bug in the kernel wireless stack, when done on wireless interfaces this could cause the wireless association to be los...

kernel: open() call allows setgid bit when user is not in new file's group

fs/open.c in the Linux kernel before 2.6.22 does not properly strip setuid and setgid bits when there is a write to a file, which allows local users to gain the privileges of a different group, and obtain sensitive information or possibly have unspecified other impact, by creating an executable...

CIFS signing sec= mount options don't work correctly

The Linux kernel before 2.6.23-rc1 checks the wrong global variable for the CIFS sec mount option, which might allow remote attackers to spoof CIFS network traffic that the client configured for security signatures, as demonstrated by lack of signing despite sec=ntlmv2i in a SetupAndX request...

Tracing execution of a threaded executable causes kernel BUG report

The utrace support in Linux kernel 2.6.18, and other versions, allows local users to cause a denial of service system hang related to "MT exec + utraceattach spin failure mode," as demonstrated by ptrace-thrash.c...

Bug in IO bitmap handling? Probably exploitable (2.6.5)

Hello. The attached is the small program that tries to write 0x20 to port 0x20. Normally this should cause SIGSEGV, so the program should crash. I think there is a bug in the 2.6 kernels though, which makes it to not crash if some trivial conditions are met. Basically it seems that if any process...
