CVE-2024-50264

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: Initialization of the dangling pointer occurring in vsk->trans During loopback communication, a dangling pointer can be created in vsk->trans, potentially leading to a Use-After-Free condition. This issue is resolved by initializing vsk->trans to NULL.

This update for the Linux Kernel 5.14.21-150400_24_119 fixes several issues. The following security issues were fixed. Vsock/virtio: Initialization of the dangling pointer occurring in vsk->trans. Ipv6: avoid use-after-free in ip6_fragment. Tcp: Use refcount_inc_not_zero in tcp_twsk_unique. Fixed memory leak for not ip packets. Fixed int overflow for stack access size. Sch_cake: do not call cake_destroy from cake_init. Fixed potential UAF in is_valid_oplock_break. Smb: client: fix use-after-free bug in cifs_debug_data_proc_show. Fixed potential UAF in smb2_is_network_name_deleted. Fixed potential UAF in cifs_stats_proc_show. Fixed potential UAF in smb2_is_valid_lease_break. Fixed potential UAF in cifs_signal_cifsd_for_reconnect. Gpiolib: cdev: Fix use after free in lineinfo_changed_notify. Gpiolib: cdev: Fix use after free in lineinfo_changed_notify. Net: do not leave a dangling sk pointer, when socket creation fails hfsplus: fix uninit-value in copy_name. Fs/9p: only translate RWX permissions for plain 9P2000. Hsr: Prevent use after free in prp_create_tagged_frame. Set gtt bound flag in amdgpu_ttm_gart_bind. Fixed use-after-free bugs caused by sco_sock_timeout. Drm/client: Fully protect modes with dev->mode_config.mutex. Fixed false-positive lockdep splat for spin_lock in __unix_gc. Fixed double free of the ha->vp_map pointer. Fixed underflow in parse_server_interfaces. Fixed use-after-free in ip6_route_mpath_notify.
