CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-53044 – net/sched: sch_api: fix xa_insert() error path in tcf_block_get_ext()
https://notcve.org/view.php?id=CVE-2024-53044
In the Linux kernel, the following vulnerability has been resolved: net/sched: sch_api: fix xa_insert() error path in tcf_block_get_ext() This command: $ tc qdisc replace dev eth0 ingress_block 1 egress_block 1 clsact Error: block dev insert failed: -EBUSY. fails because user space requests the same block index to be set for both ingress and egress. [ side note, I don't think it even failed prior to commit 913b47d3424e ("net/sched: Introduce tc block netdev tracking infra"), because this is a command from an old set of notes of mine which used to work, but alas, I did not scientifically bisect this ] The problem is not that it fails, but rather, that the second time around, it fails differently (and irrecoverably): $ tc qdisc replace dev eth0 ingress_block 1 egress_block 1 clsact Error: dsa_core: Flow block cb is busy. [ another note: the extack is added by me for illustration purposes. the context of the problem is that clsact_init() obtains the same &q->ingress_block pointer as &q->egress_block, and since we call tcf_block_get_ext() on both of them, "dev" will be added to the block->ports xarray twice, thus failing the operation: once through the ingress block pointer, and once again through the egress block pointer. the problem itself is that when xa_insert() fails, we have emitted a FLOW_BLOCK_BIND command through ndo_setup_tc(), but the offload never sees a corresponding FLOW_BLOCK_UNBIND. ] Even correcting the bad user input, we still cannot recover: $ tc qdisc replace dev swp3 ingress_block 1 egress_block 2 clsact Error: dsa_core: Flow block cb is busy. Basically the only way to recover is to reboot the system, or unbind and rebind the net device driver. To fix the bug, we need to fill the correct error teardown path which was missed during code movement, and call tcf_block_offload_unbind() when xa_insert() fails. [ last note, fundamentally I blame the label naming convention in tcf_block_get_ext() for the bug. • https://git.kernel.org/stable/c/94e2557d086ad831027c54bc9c2130d337c72814 https://git.kernel.org/stable/c/8966eb69a143b1c032365fe84f2815f3c46f2590 https://git.kernel.org/stable/c/a13e690191eafc154b3f60afe9ce35aa9b9128b4 •

In the Linux kernel, the following vulnerability has been resolved: mctp i2c: handle NULL header address daddr can be NULL if there is no neighbour table entry present, in that case the tx packet should be dropped. saddr will usually be set by MCTP core, but check for NULL in case a packet is transmitted by a different protocol. • https://git.kernel.org/stable/c/f5b8abf9fc3dacd7529d363e26fe8230935d65f8 https://git.kernel.org/stable/c/4707893315802a0917231b94cb20cbe50ccbfe03 https://git.kernel.org/stable/c/8e886e44397ba89f6e8da8471386112b4f5b67b7 https://git.kernel.org/stable/c/8c222adadc1612e4f097688875962a28e3f5ab44 https://git.kernel.org/stable/c/01e215975fd80af81b5b79f009d49ddd35976c13 •
