In the Linux kernel, the following vulnerability has been resolved: HID: core: Harden s32ton() against conversion to 0 bits Testing by the syzbot fuzzer showed that the HID core gets a shift-out-of-bounds exception when it tries to convert a 32-bit quantity to a 0-bit quantity. Ideally this should never occur, but there are buggy devices and some might have a report field with size set to zero; we shouldn't reject the report or the device just because of that. Instead, harden the s32ton() routine so that it returns a reasonable result instead of crashing when it is called with the number of bits set to 0 -- the same as what snto32() does.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.48-1.

    We recommend that you upgrade your linux packages.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - HID: core: Harden s32ton() against conversion to 0 bits Testing by the syzbot fuzzer showed that the HID     core gets a shift-out-of-bounds exception when it tries to convert a 32-bit quantity to a 0-bit quantity.
    Ideally this should never occur, but there are buggy devices and some might have a report field with size     set to zero; we shouldn't reject the report or the device just because of that. Instead, harden the     s32ton() routine so that it returns a reasonable result instead of crashing when it is called with the     number of bits set to 0 -- the same as what snto32() does. (CVE-2025-38556)

Note that Nessus relies on the presence of the package as reported by the vendor.
