** Description changed: + [ Impact ] + + Due to a false negative result of runtime bounds checking, a kernel + panic occurrs on reception of erspan packet. + + A bug has been discovered in the kernel networking code for handling of + erspan packets. It manifests itself when FORTIFY_SOURCE is enabled and + GCC 15.2+ compiler is used, both of which are true for Ubuntu Questing + and onwards. + + [ Testc Plan ] + + The Open vSwitch system test suite triggers the panic, and consequentliy + it can be used to confirm the fix. + + [ Where problems could occur ] + + The false negative occurs due to incorrect order of referencing counter + and the data protected by it, the fix is trivial and has been merged + both to mainline and stable for some time. + + Probability of it causing undesired effects is minimal. + + [ Other info ] + Steps to reproduce the issue: 1. sudo apt build-dep openvswitch 2. git clone https://github.com/openvswitch/ovs.git 3. cd ovs 4. ./boot.sh && ./configure && make -j$(nproc) 5. sudo make check-kernel TESTSUITEFLAGS="-j1 18" [ 70.856928] kernel BUG at lib/string_helpers.c:1043!
