CVE-2024-49946 ppp: do not assume bh is held in ppp_channel_bridge_input()

In the Linux kernel, the following vulnerability has been resolved: ppp: do not assume bh is held in pppchannelbridgeinput Networking receive path is usually handled from BH handler. However, some protocols need to acquire the socket lock, and packets might be stored in the socket backlog is the...

CVE-2024-49946

CVE-2024-49946 affects the Linux kernel PPP stack. The issue arises in ppp_channel_bridge_input() when packets are backlogged to a socket owned by a user process and the code path can call sk_backlog_rcv()/__release_sock()/release_sock() in process context. This creates an inconsistent lock state...

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.6.58 Description: The issue is related to the Linux kernel's rcu/nocb functionality, where a CPU set offline can still enqueue callbacks from a softirq, leading to a deferred rcuog wake-up through an IPI to an...

kernel: wifi: mac80211: Fix deadlock in ieee80211_sta_ps_deliver_wakeup()

A vulnerability was found in the Linux kernel's mac80211 component within the ieee80211stapsdeliverwakeup function, where improper locking of the sta-pslock can lead to a deadlock condition, which occurs because the function uses a spin lock without preventing softirq execution on the same CPU,...
