CVSS: -EPSS: 0%CPEs: 6EXPL: 0CVE-2024-47734 – bonding: Fix unnecessary warnings and logs from bond_xdp_get_xmit_slave()
https://notcve.org/view.php?id=CVE-2024-47734
In the Linux kernel, the following vulnerability has been resolved: bonding: Fix unnecessary warnings and logs from bond_xdp_get_xmit_slave() syzbot reported a WARNING in bond_xdp_get_xmit_slave. To reproduce this[1], one bond device (bond1) has xdpdrv, which increases bpf_master_redirect_enabled_key. Another bond device (bond0) which is unsupported by XDP but its slave (veth3) has xdpgeneric that returns XDP_TX. This triggers WARN_ON_ONCE() from the xdp_master_redirect(). To reduce unnecessary warnings and improve log management, we need to delete the WARN_ON_ONCE() and add ratelimit to the netdev_err(). [1] Steps to reproduce: # Needs tx_xdp with return XDP_TX; ip l add veth0 type veth peer veth1 ip l add veth3 type veth peer veth4 ip l add bond0 type bond mode 6 # BOND_MODE_ALB, unsupported by XDP ip l add bond1 type bond # BOND_MODE_ROUNDROBIN by default ip l set veth0 master bond1 ip l set bond1 up # Increases bpf_master_redirect_enabled_key ip l set dev bond1 xdpdrv object tx_xdp.o section xdp_tx ip l set veth3 master bond0 ip l set bond0 up ip l set veth4 up # Triggers WARN_ON_ONCE() from the xdp_master_redirect() ip l set veth3 xdpgeneric object tx_xdp.o section xdp_tx • https://git.kernel.org/stable/c/9e2ee5c7e7c35d195e2aa0692a7241d47a433d1e https://git.kernel.org/stable/c/c1be35e774f8ed415e01209fddd963c5a74e8e9f https://git.kernel.org/stable/c/6b64197b4bf1a5703a8b105367baf20f1e627a75 https://git.kernel.org/stable/c/ccd3e6ff05e5236d1b9535f23f3e6622e0bb32b8 https://git.kernel.org/stable/c/72e2c0825a480e19ee999cee9d018850d38c82b9 https://git.kernel.org/stable/c/57b5fba55c6f8b1d83312a34bd656166fcd95658 https://git.kernel.org/stable/c/0cbfd45fbcf0cb26d85c981b91c62fe73cdee01c •
CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-47730 – crypto: hisilicon/qm - inject error before stopping queue
https://notcve.org/view.php?id=CVE-2024-47730
In the Linux kernel, the following vulnerability has been resolved: crypto: hisilicon/qm - inject error before stopping queue The master ooo cannot be completely closed when the accelerator core reports memory error. Therefore, the driver needs to inject the qm error to close the master ooo. Currently, the qm error is injected after stopping queue, memory may be released immediately after stopping queue, causing the device to access the released memory. Therefore, error is injected to close master ooo before stopping queue to ensure that the device does not access the released memory. • https://git.kernel.org/stable/c/6c6dd5802c2d6769fa589c0e8de54299def199a7 https://git.kernel.org/stable/c/98d3be34c9153eceadb56de50d9f9347e88d86e4 https://git.kernel.org/stable/c/aa3e0db35a60002fb34ef0e4ad203aa59fd00203 https://git.kernel.org/stable/c/f8024f12752e32ffbbf59e1c09d949f977ff743f https://git.kernel.org/stable/c/c5f5b813e546f7fe133539c3d7a5086cc8dd2aa1 https://git.kernel.org/stable/c/b04f06fc0243600665b3b50253869533b7938468 •
CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-47728 – bpf: Zero former ARG_PTR_TO_{LONG,INT} args in case of error
https://notcve.org/view.php?id=CVE-2024-47728
In the Linux kernel, the following vulnerability has been resolved: bpf: Zero former ARG_PTR_TO_{LONG,INT} args in case of error For all non-tracing helpers which formerly had ARG_PTR_TO_{LONG,INT} as input arguments, zero the value for the case of an error as otherwise it could leak memory. For tracing, it is not needed given CAP_PERFMON can already read all kernel memory anyway hence bpf_get_func_arg() and bpf_get_func_ret() is skipped in here. Also, the MTU helpers mtu_len pointer value is being written but also read. Technically, the MEM_UNINIT should not be there in order to always force init. Removing MEM_UNINIT needs more verifier rework though: MEM_UNINIT right now implies two things actually: i) write into memory, ii) memory does not have to be initialized. If we lift MEM_UNINIT, it then becomes: i) read into memory, ii) memory must be initialized. This means that for bpf_*_check_mtu() we're readding the issue we're trying to fix, that is, it would then be able to write back into things like .rodata BPF maps. Follow-up work will rework the MEM_UNINIT semantics such that the intent can be better expressed. • https://git.kernel.org/stable/c/d7a4cb9b6705a89937d12c8158a35a3145dc967a https://git.kernel.org/stable/c/8397bf78988f3ae9dbebb0200189a62a57264980 https://git.kernel.org/stable/c/a634fa8e480ac2423f86311a602f6295df2c8ed0 https://git.kernel.org/stable/c/599d15b6d03356a97bff7a76155c5604c42a2962 https://git.kernel.org/stable/c/594a9f5a8d2de2573a856e506f77ba7dd2cefc6a https://git.kernel.org/stable/c/4b3786a6c5397dc220b1483d8e2f4867743e966f •
