CVE-2023-52472

crypto: rsa - add a check for allocation failure

Published Feb 25, 2024 CVSS 3.1 · 5.5 Medium EPSS < 1% KEV · Not listed
Description
In the Linux kernel, the following vulnerability has been resolved:

crypto: rsa - add a check for allocation failure

Static checkers insist that the mpi_alloc() allocation can fail so add
a check to prevent a NULL dereference. Small allocations like this
can't actually fail in current kernels, but adding a check is very
simple and makes the static checkers happy.

Remediation

No solution or workaround provided in the CVE record
