medium Tenable Self-Hosted Container Security Plugin ID 457132

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: usb: atm: cxacru: fix a flaw in
 existing endpoint checks Syzbot once again identified a flaw in usb endpoint checking, see [1]. This time
 the issue stems from a commit authored by me (2eabb655a968 ("usb: atm: cxacru: fix endpoint checking in
 cxacru_bind()")). While using usb_find_common_endpoints() may usually be enough to discard devices with
 wrong endpoints, in this case one needs more than just finding and identifying the sufficient number of
 endpoints of correct types - one needs to check the endpoint's address as well. Since cxacru_bind() fills
 URBs with CXACRU_EP_CMD address in mind, switch the endpoint verification approach to
 usb_check_XXX_endpoints() instead to fix incomplete ep testing. [1] Syzbot report: usb 5-1: BOGUS urb
