In this case, when it arms a # breakpoint on the probe address, it may cause a use-after-free. # # To fix this issue, only use `__module_text_address()` once and get a # reference to the module then. If it fails, reject the probe" # # * tag 'probes-fixes-v6.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: # kprobes: Fix possible use-after-free issue on kprobe registration # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 e8c39d0f57f358950356a8e44ee5159f57f86ec5 # make -s -j 32 ARCH=mips O=/kisskb/build/linus_allnoconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- allnoconfig # < make -s -j 32 ARCH=mips O=/kisskb/build/linus_allnoconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 32 ARCH=mips O=/kisskb/build/linus_allnoconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 32 ARCH=mips O=/kisskb/build/linus_allnoconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- Completed OK # rm -rf /kisskb/build/linus_allnoconfig_mips-gcc13 # Build took: 0:00:27.300513
