Linux kernel BPF Denial of Service Vulnerability

Linux kernel is an open source operating system. Linux kernel bpf has a security vulnerability that allows local attackers to conduct denial of service attacks...

USN-2965-4 linux-snapdragon vulnerability

Jann Horn discovered that the extended Berkeley Packet Filter eBPF implementation in the Linux kernel did not properly reference count file descriptors, leading to a use-after-free. A local unprivileged attacker could use this to gain administrative privileges. Ralf Spenneberg discovered that the...

USN-2965-3 linux-raspi2 vulnerabilities

Jann Horn discovered that the extended Berkeley Packet Filter eBPF implementation in the Linux kernel did not properly reference count file descriptors, leading to a use-after-free. A local unprivileged attacker could use this to gain administrative privileges. CVE-2016-4557 Ralf Spenneberg...

USN-2947-2 linux-lts-wily vulnerabilities

Ralf Spenneberg discovered that the usbvision driver in the Linux kernel did not properly validate the interfaces and endpoints reported by the device. An attacker with physical access could cause a denial of service system crash. CVE-2015-7833 Venkatesh Pottem discovered a use-after-free...

USN-2947-2: Linux kernel (Wily HWE) vulnerabilities

Ralf Spenneberg discovered that the usbvision driver in the Linux kernel did not properly validate the interfaces and endpoints reported by the device. An attacker with physical access could cause a denial of service system crash. CVE-2015-7833 Venkatesh Pottem discovered a use-after-free...

kernel: Crafted BPF filters may crash kernel during JIT optimisation

A flaw was found in the kernel's implementation of the Berkeley Packet Filter BPF. A local attacker could craft BPF code to crash the system by creating a situation in which the JIT compiler would fail to correctly optimize the JIT image on the last pass. This would lead to the CPU executing...

Debian DSA-3329-1 : linux - security update

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leak. - CVE-2015-1333 Colin Ian King discovered a flaw in the addkey function of the Linux kernel's keyring subsystem. A local user can exploit this flaw to...

UBUNTU-CVE-2015-4700

The bpfintjitcompile function in arch/x86/net/bpfjitcomp.c in the Linux kernel before 4.0.6 allows local users to cause a denial of service system crash by creating a packet filter and then loading crafted BPF instructions that trigger late convergence by the JIT compiler...

UBUNTU-CVE-2014-3145

The BPFSANCNLATTRNEST extension implementation in the skrunfilter function in net/core/filter.c in the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users to cause a denial of service over-read and system crash via crafted BPF instructions. NOTE:...

DEBIAN-CVE-2014-2889

Off-by-one error in the bpfjitcompile function in arch/x86/net/bpfjitcomp.c in the Linux kernel before 3.1.8, when BPF JIT is enabled, allows local users to cause a denial of service system crash or possibly gain privileges via a long jump after a conditional jump...

kernel: socket filters infoleak

The skrunfilter function in net/core/filter.c in the Linux kernel before 2.6.36.2 does not check whether a certain memory location has been initialized before executing a 1 BPFSLDMEM or 2 BPFSLDXMEM instruction, which allows local users to obtain potentially sensitive information from kernel stac...
