CVE-2022-49789 scsi: zfcp: Fix double free of FSF request when qdio send fails

In the Linux kernel, the following vulnerability has been resolved: scsi: zfcp: Fix double free of FSF request when qdio send fails We used to use the wrong type of integer in 'zfcpfsfreqsend' to cache the FSF request ID when sending a new FSF request. This is used in case the sending fails and w...

CVE-2022-49775

CVE-2022-49775 (Linux kernel) affects the tcp_cdg congestion control. The advisory notes that when MPTCP calls tcp_disconnect() on an already-disconnected flow under CDG, it may trigger a double-free in the SLAB allocator. The vulnerability arises from the ability to call tcp_cdg_release() multip...

CVE-2022-49775 tcp: cdg: allow tcp_cdg_release() to be called multiple times

In the Linux kernel, the following vulnerability has been resolved: tcp: cdg: allow tcpcdgrelease to be called multiple times Apparently, mptcp is able to call tcpdisconnect on an already disconnected flow. This is generally fine, unless current congestion control is CDG, because it might trigger...

CVE-2022-49768

CVE-2022-49768 is associated with the Linux kernel 9p subsystem, specifically in trans_fd/p9_conn_cancel, where a double-lock issue was reported by syzbot and is mitigated by dropping the client lock earlier after requests move to the local list. Public sources in connected documents (Astra Linux...
