Vulnerability CVE-2023-52653
Published: 2024-05-01

Description:
In the Linux kernel, the following vulnerability has been resolved:

SUNRPC: fix a memleak in gss_import_v2_context

The ctx->mech_used.data allocated by kmemdup is not freed in neither
gss_import_v2_context nor it only caller gss_krb5_import_sec_context,
which frees ctx on error.

Thus, this patch reform the last call of gss_import_v2_context to the
gss_krb5_import_ctx_v2, preventing the memleak while keepping the return
formation.
