Meta Katran Security Vulnerability

Meta Katran is a C++ library and BPF program from Meta Corporation. It is used to build high-performance Layer 4 load-balanced forwarding planes. A security vulnerability exists in Meta Katran that stems from the ability to expose uninitialized kernel memory as part of an IP header...

kernel: Rate limit overflow messages in r8152 in intr_callback

A vulnerability was found in intrcallback in drivers/net/usb/r8152.c in the BPF component in the Linux Kernel. The manipulation leads to logging excessive data, where an attack can be launched remotely...

kernel: LSM: general protection fault in legacy_parse_param

In the Linux kernel, the following vulnerability has been resolved: LSM: general protection fault in legacyparseparam The usual LSM hook "bail on fail" scheme doesn't work for cases where a security module may return an error code indicating that it does not recognize an input. In this particular...

kernel: bpf, arm64: Fixed a BTI error on returning to patched function

A control-flow integrity flaw was found in the Linux kernel on the arm64 architecture within the extended Berkeley Packet Filter trampoline return path. Returning to a patched function with an instruction sequence that fails the branch-target security check can trigger an exception and panic. A...
