Linux: Integer Underflow (Wrap or Wraparound)
CVE-2024-53061 is a high-severity integer underflow (wrap or wraparound) vulnerability in Linux, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists versions c5f6fefcda8fac8f082b6c5bf416567f4e100c51, e5117f6e7adcf9fd7546cdd0edc9abe4474bc98b, f54e8e1e39dacccebcfb9a9a36f0552a0a97e2ef as the first without the flaw, so updating Linux to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.3% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Linux to c5f6fefcda8fac8f082b6c5bf416567f4e100c51 or e5117f6e7adcf9fd7546cdd0edc9abe4474bc98b or f54e8e1e39dacccebcfb9a9a36f0552a0a97e2ef or a930cddfd153b5d4401df0c01effa14c831ff21e, whichever matches your release line, or a later version.
- Update Linux Kernel to 4.19.324 or 5.4.286 or 5.10.230 or 5.15.172, whichever matches your release line, or a later version.

Official description
In the Linux kernel, the following vulnerability has been resolved: media: s5p-jpeg: prevent buffer overflows The current logic allows word to be less than 2. If this happens, there will be buffer overflows, as reported by smatch. Add extra checks to prevent it. While here, remove an unused word = 0 assignment.

The underlying weakness: Integer Underflow (Wrap or Wraparound)
The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
