https://notcve.org/view.php?id=CVE-2024-38567
In the Linux kernel, the following vulnerability has been resolved: wifi: carl9170: add a proper sanity check for endpoints Syzkaller reports [1] hitting a warning which is caused by presence of a wrong endpoint type at the URB sumbitting stage. While there was a check for a specific 4th endpoint, since it can switch types between bulk and interrupt, other endpoints are trusted implicitly. Similar warning is triggered in a couple of other syzbot issues [2]. Fix the issue by doing a comprehensive check of all endpoints taking into account difference between high- and full-speed configuration. [1] Syzkaller report: ...

CVSS: 4.4EPSS: 0%CPEs: 4EXPL: 0CVE-2024-38564 – bpf: Add BPF_PROG_TYPE_CGROUP_SKB attach type enforcement in BPF_LINK_CREATE
https://notcve.org/view.php?id=CVE-2024-38564
In the Linux kernel, the following vulnerability has been resolved: bpf: Add BPF_PROG_TYPE_CGROUP_SKB attach type enforcement in BPF_LINK_CREATE bpf_prog_attach uses attach_type_to_prog_type to enforce proper attach type for BPF_PROG_TYPE_CGROUP_SKB. link_create uses bpf_prog_get and relies on bpf_prog_attach_check_attach_type to properly verify prog_type <> attach_type association. Add missing attach_type enforcement for the link_create case. Otherwise, it's currently possible to attach cgroup_skb prog types to other cgroup hooks. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: bpf: agregue la aplicación del tipo de archivo adjunto BPF_PROG_TYPE_CGROUP_SKB en BPF_LINK_CREATE bpf_prog_attach usa adjunto_type_to_prog_type para aplicar el tipo de archivo adjunto adecuado para BPF_PROG_TYPE_CGROUP_SKB. link_create usa bpf_prog_get y se basa en bpf_prog_attach_check_attach_type para verificar correctamente la asociación prog_type <> adjunto_tipo. Agregue la aplicación de adjunto_tipo faltante para el caso link_create. De lo contrario, actualmente es posible adjuntar tipos de programa cgroup_skb a otros enlaces de cgroup. • https://git.kernel.org/stable/c/4a1e7c0c63e02daad751842b7880f9bbcdfb6e89 https://git.kernel.org/stable/c/6675c541f540a29487a802d3135280b69b9f568d https://git.kernel.org/stable/c/67929e973f5a347f05fef064fea4ae79e7cdb5fd https://git.kernel.org/stable/c/b34bbc76651065a5eafad8ddff1eb8d1f8473172 https://git.kernel.org/stable/c/543576ec15b17c0c93301ac8297333c7b6e84ac7 https://access.redhat.com/security/cve/CVE-2024-38564 https://bugzilla.redhat.com/show_bug.cgi?id=2293429 • CWE-665: Improper Initialization •

In the Linux kernel, the following vulnerability has been resolved: scsi: bfa: Ensure the copied buf is NUL terminated Currently, we allocate a nbytes-sized kernel buffer and copy nbytes from userspace to that buffer. Later, we use sscanf on this buffer but we don't ensure that the string is terminated inside the buffer, this can lead to OOB read when using sscanf. Fix this issue by using memdup_user_nul instead of memdup_user. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: scsi: bfa: asegúrese de que el buf copiado tenga terminación NUL.
