CVE-2022-48822

In the Linux kernel, the following vulnerability has been resolved: usb: ffs: Fix use-after-free for epfile Consider a case where ffsfuncepsdisable is called from ffsfuncdisable as part of composition switch and at the same time ffsepfilerelease get called from userspace. ffsepfilerelease will fr...

CVE-2022-48822

CVE-2022-48822 — Linux kernel usb f_fs use-after-free (epfile) Technical summary: A race between ffs_func_eps_disable (which uses a local copy of epfiles) and ffs_epfile_release can lead to use-after-free of the epfile read buffer. While ffs_epfile_release frees the buffer and destroys ffs->ep...

Linux kernel security vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel, which originates from a competitive condition vulnerability in the usb:gadget:ffs module...

CVE-2021-46933

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: ffs: Clear ffseventfd in ffsdataclear. ffsdataclear is indirectly called from both ffsfskillsb and ffsep0release, so it ends up being called twice when userland closes ep0 and then unmounts ffs. If userland provided ...
