CVE-2024-53042

CVE-2024-53042 affects the Linux kernel’s ipv4/ip_tunnel code. The issue arises from paths where ip_tunnel_init_flow() is invoked without holding the RCU read lock, triggering a suspicious RCU usage warning. The fix uses l3mdev_master_upper_ifindex_by_index() to acquire the RCU read lock before c...

CVE-2024-50304

The CVE-2024-50304 entry concerns the Linux kernel IPv4 ip_tunnel subsystem. A suspicious RCU usage warning in ip_tunnel_find() was addressed by adding a lockdep check to hlist_for_each_entry_rcu(), validating that the RTNL mutex is held. The per-netns IP tunnel hash table is protected by the RTN...

In the Linux kernel, the following vulnerability has been resolved: aio: fix use-after-free due to missing POLLFREE handling signalfdpoll and binderpoll are special in that they use a waitqueue whose lifetime is the current task, rather than the struct file as is normally the case. This is okay f...

kernel: i2c: core: Run atomic i2c xfer when !preemptible

In the Linux kernel, the following vulnerability has been resolved: i2c: core: Run atomic i2c xfer when !preemptible Since bae1d3a05a8b, i2c transfers are non-atomic if preemption is disabled. However, non-atomic i2c transfers require preemption e.g. in waitforcompletion while waiting for the DMA...
