CVE-2022-49776 macvlan: enforce a consistent minimal mtu

In the Linux kernel, the following vulnerability has been resolved: macvlan: enforce a consistent minimal mtu macvlan should enforce a minimal mtu of 68, even at link creation. This patch avoids the current behavior which could lead to crashes in ipv6 stack if the link is brought up $ ip link add...

CVE-2022-49776

CVE-2022-49776 affects the Linux kernel macvlan code; it fixes a low-level issue by enforcing a minimal MTU of 68 at link creation to prevent crashes in the IPv6 stack. The advisory notes that macvlan0 should reject mtu values below the device minimum (e.g., 67 rejected, 68 accepted), with the fi...

CVE-2022-49774

CVE-2022-49774 affects the Linux kernel (KVM: x86/xen) and concerns eventfd error handling in kvm_xen_eventfd_assign(). The root cause was calling eventfd_ctx_put() on error; a patch introduces a new goto target to handle the error instead. The documents confirm the fix has been applied and refer...

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-2022-49769

CVE-2022-49769 corresponds to a Linux kernel fix for the gfs2 filesystem: after reading a superblock, the sb_bsize_shift field is now validated to match the expected value, preventing shift/out-of-bounds and related mount errors. The available details describe the root cause (unchecked sb_bsize_s...

CVE-2022-49767 9p/trans_fd: always use O_NONBLOCK read/write

In the Linux kernel, the following vulnerability has been resolved: 9p/transfd: always use ONONBLOCK read/write syzbot is reporting hung task at p9fdclose 1, for p9muxpollstop from p9conndestroy from p9fdclose is failing to interrupt already started kernelread from p9fdread from p9readwork and/or...

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...

CVE-2022-49768 9p: trans_fd/p9_conn_cancel: drop client lock earlier

In the Linux kernel, the following vulnerability has been resolved: 9p: transfd/p9conncancel: drop client lock earlier syzbot reported a double-lock here and we no longer need this lock after requests have been moved off to local list: just drop the lock earlier...

CVE-2022-49767

CVE-2022-49767 affects the Linux kernel 9p/trans_fd path. The issue arises because p9_mux_poll_stop() could fail to interrupt blocking kernel_read()/kernel_write() on pipes due to fd_open() not setting O_NONBLOCK, whereas socket paths already use O_NONBLOCK. A minimal patch makes O_NONBLOCK alway...
