Descriptions
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.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: SUNRPC: corrige una fuga de memport en gss_import_v2_context El ctx->mech_used.data asignado por kmemdup no se libera ni en gss_import_v2_context ni solo en el llamador gss_krb5_import_sec_context, lo que libera a ctx en caso de error. Por lo tanto, este parche reforma la última llamada de gss_import_v2_context a gss_krb5_import_ctx_v2, evitando la fuga de memoria y manteniendo la formación de retorno.
