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

wifi: mac80211: always free skb on ieee80211_tx_prepare_skb() failure

ieee80211_tx_prepare_skb() has three error paths, but only two of them free the skb. The first error path (ieee80211_tx_prepare() returning TX_DROP) does not free it, while invoke_tx_handlers() failure and the fragmentation check both do.

Add kfree_skb() to the first error path so all three are consistent, and remove the now-redundant frees in callers (ath9k, mt76, mac80211_hwsim) to avoid double-free.

Document the skb ownership guarantee in the function's kdoc.

Affected: openEuler:24.03-LTS: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

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

mptcp: Initialise rcv_mss before calling tcp_send_active_reset() in mptcp_do_fastclose().

syzbot reported divide-by-zero in __tcp_select_window() by MPTCP socket. [0]

We had a similar issue for the bare TCP and fixed in commit 499350a5a6e7 ("tcp: initialize rcv_mss to TCP_MIN_MSS instead of 0").

Let's apply the same fix to mptcp_do_fastclose().
