CVE-2024-27013 – tun: limit printing rate when illegal packet received by tun dev
https://notcve.org/view.php?id=CVE-2024-27013
01 May 2024 — In the Linux kernel, the following vulnerability has been resolved: tun: limit printing rate when illegal packet received by tun dev vhost_worker will call tun call backs to receive packets. If too many illegal packets arrives, tun_do_read will keep dumping packet contents. When console is enabled, it will costs much more cpu time to dump packet and soft lockup will be detected. net_ratelimit mechanism can be used to limit the dumping rate.

CVE-2024-27012 – netfilter: nf_tables: restore set elements when delete set fails

01 May 2024 — In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: restore set elements when delete set fails From abort path, nft_mapelem_activate() needs to restore refcounters to the original state. Currently, it uses the set->ops->walk() to iterate over these set elements. The existing set iterator skips inactive elements in the next generation, this does not work from the abort path to restore the original state since it has to skip active elements instead (not inactive ones).

01 May 2024 — In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: fix memleak in map from abort path The delete set command does not rely on the transaction object for element removal, therefore, a combination of delete element + delete set from the abort path could result in restoring twice the refcount of the mapping. Check for inactive element in the next generation for the delete element command in the abort path, skip restoring state if next generation bit has been already clear... • https://git.kernel.org/stable/c/591054469b3eef34bc097c30fae8ededddf8d796 •

CVE-2024-27009 – s390/cio: fix race condition during online processing

01 May 2024 — In the Linux kernel, the following vulnerability has been resolved: s390/cio: fix race condition during online processing A race condition exists in ccw_device_set_online() that can cause the online process to fail, leaving the affected device in an inconsistent state. As a result, subsequent attempts to set that device online fail with return code ENODEV. The problem occurs when a path verification request arrives after a wait for final device state completed, but before the result state is evaluated.

CVE-2024-27005 – interconnect: Don't access req_list while it's being manipulated

01 May 2024 — In the Linux kernel, the following vulnerability has been resolved: interconnect: Don't access req_list while it's being manipulated The icc_lock mutex was split into separate icc_lock and icc_bw_lock mutexes in [1] to avoid lockdep splats. However, this didn't adequately protect access to icc_node::req_list. The icc_set_bw() function will eventually iterate over req_list while only holding icc_bw_lock, but req_list can be modified while only holding icc_lock. This causes races between icc_set_bw(), of_icc_... • https://git.kernel.org/stable/c/af42269c3523492d71ebbe11fefae2653e9cdc78 •
