NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-debug-devel-matched package and not the kernel-64k-debug-devel-matched package as distributed by AlmaLinux.

In the Linux kernel, the following vulnerability has been resolved:

net: use dst_dev_rcu() in sk_setup_caps()

Use RCU to protect accesses to dst->dev from sk_setup_caps() and sk_dst_gso_max_size().

Also use dst_dev_rcu() in ip6_dst_mtu_maybe_forward(), and ip_dst_mtu_maybe_forward().

ip4_dst_hoplimit() can use dst_dev_net_rcu().
