CVE-2022-50259

CVE-2022-50259 : In the Linux kernel, the bpf sock_map_free() path can trigger use-after-free because sock_map_free() calls release_sock(sk) without holding a socket reference. This race is evidenced by syzbot tracing and mirrors a related issue fixed in sock_hash_free() (commit referenced). The ...

CVE-2022-50248

CVE-2022-50248 is a Linux kernel vulnerability affecting the iwlwifi/iwl mvm TX path where a double-free of skb can occur. The issue arises when iwl_mvm_tx_skb_sta returns non-zero and the skb is freed, but a TSO skb buffer may also be freed in an error path; the fix is to return 0 in that error ...
