NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-debug-devel package and not the kernel-rt-debug-devel package as distributed by Rocky-Linux. See How to fix? for Rocky-Linux:8 relevant fixed versions and status.

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.
